ESCRIPTION

The Dimension CP-Series are cost optimized power supplies without compromising quality, reliability and performance.

First of all, high immunity to transients and power surges as well as low electromagnetic emission and Marine approvals with

EMC Class B make the CP20.245-R2 the best choice for equipment in bridge & deck zones the same way as for oil, gas and chemical plants.

This power supply furthermore features a DC-OK signal contact to remotely monitor error-free operation, a decoupling MOSFET to set-up redundant power supply systems, and plug connector terminals to allow device replacement while the application keeps running. The CP20.245-R2 covers an extreme wide temperature range from -40°C up to +60°C providing full output power.

Outstanding features of CP20.245-R2 are its high efficiency, the electronic inrush current limitation, and an active PFC. The power supply has a power reserve of 20% included, which may even be used continuously at temperatures up to +45°C.

Additionally, the device can deliver about 3 times the nominal output current for 12ms which helps to trip fuses on faulty output branches.

**) Hiccup PLUS ® Mode

At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s. After this, the output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been

cleared, the device will operate normally. See Fig. 6-2.

The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime expectancy of the builtin electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated acco rding to the capacitor’s manu facturer specification.

The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years (131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.

MTBF stands for M ean T ime B etween F ailure, which is calculated according to statistical device failures, and indicates reliability of a device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.

The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it cannot be determined if the failed unit has been running for 50 000h or only for 100h.

APABILITY

The device has a power reserve of 20% included, which may even be used continuously at temperatures up to +45°C. Additionally, it can deliver about 3 times the nominal output current for 12ms which helps to trip fuses on faulty output branches or to start peak current demanding loads. Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady-state current and usually exceeds the nominal output current

(including the PowerBoost). The same situation applies when starting a capacitive load.

The following examples show typical voltage dips:

A voltage adjustment potentiometer can be found behind the flap on the front of the unit (see chapter 14). However, it is not

recommended to change the output voltage since load sharing between power supplies connected in parallel can only be achieved by a precise setting of the output voltage. This is the case with the factory settings.

Only trained personnel should operate the voltage adjustment potentiometer.

Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force).

This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is on or off.

The unit is tested and approved for branch circuits up to 30A (UL) and 32A (IEC). An external protection is only required if the supplying branch has an ampacity greater than this. Check also local codes and local requirements. In some countries local regulations might apply.

If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of the circuit breaker. A minimum value of 10A B- or C-Characteristic breaker should be used.

Standard miniature circuit breakers (MCB ’s or UL 1077 circuit breakers) are commonly used for AC-supply systems and may also be used on 24V branches.

MCB’s are designed to protect wires and circuits. If the ampere value and the characteristics of the MCB are adapted to the wire size that is used, the wiring is considered as thermally safe regardless of whether the MCB opens or not.

To avoid voltage dips and under-voltage situations in adjacent 24V branches which are supplied by the same source, a fast (magnetic) tripping of the MCB is desired. A quick shutdown within 10ms is necessary corresponding roughly to the ride-through time of PLC's. This requires power supplies with high current reserves and large output capacitors. Furthermore, the impedance of the faulty branch must be sufficiently small in order for the current to actually flow. The best current reserve in the power supply does not help if Ohm’s law does not permit current flow. The following table has typical test results showing which B- and C-Characteristic MCBs magnetically trip depending on the wire cross section and wire length.

PERATION

Power supplies of the same type can be connected in series for higher output voltages. It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150Vdc. Voltages with a potential above 60Vdc are not SELV anymore and can be dangerous. Such voltages must be installed with a protection against touching.

Power supplies can be paralleled to increase the output power. For redundancy applications one extra power supply is always needed for sufficient output current in case one unit fails.

The unit is permanently set to “parallel use” mode in order to achieve load sharing between power supplies connected in parallel. The “Parallel use” mode regulates the output voltage in such a manner that the voltage at no load is approx. 4% higher than

at nominal load. See also chapter 6.

Energize all units at the same time to avoid the overload Hiccup PLUS mode. It also might be necessary to cycle the input power (turn-off for at least five seconds), if the output was in Hiccup PLUS mode due to overload or short circuits and the required output current is higher than the current of one unit.

Do not use power supplies in parallel in mounting orientations other than the standard mounting orientation (input terminals on bottom of the unit) or in any other condition where a derating of the output current is required (e.g. altitude).

Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.

Do not load paralleled power supplies with higher currents as shown in the following diagrams:

EDUNDANCY

Power supplies can be paralleled for redundancy to gain higher system availability. The unit is already equipped with a MOSFET as decoupling device on the output to avoid, that a defective unit becomes a load for the other power supplies and the output voltage can not be maintained any more.

Recommendations for building redundant power systems: a) Use separate input fuses for each power supply. b) Monitor the individual power supply units. Therefore, use the built-in DC-OK relay contact of the power supply.

NCLOSURE

When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside. In such situations, the inside temperature defines the ambient temperature for the power supply.

The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.

The power supply is placed in the middle of the box, no other heat producing items are inside the box

RIENTATIONS

Mounting orientations other than all terminals on the bottom require a reduction in continuous output power or a limitation in the maximum allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous operation can be found below:

Curve A1 Recommended output current.

Curve A2 Max allowed output current (results in approximately half the lifetime expectancy of A1).
