PE has the same meaning as the symbol. The symbol for Protective Earth. Earth, Ground AC 230V 230V AC 50 Hz versus 60 Hz nom typ — (alone in table cell) This document uses the term “earth” which is the same as the U.S. term “ground”. A value that is displayed with the AC or DC before the value represents a nominal voltage with standard tolerances (usually ±15%) included. For example, DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V). A value with the unit (V AC) at the end is a momentary value without any additional tolerances included. As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50 Hz mains frequency. AC 120V parameters are valid for 60 Hz mains frequency. Indicates a nominal value. Indicates a typical value. A dash alone in a table cell indicates that there is no information to be included in that cell. All values in this document are typical values under the following conditions unless otherwise noted: 230V AC 50 Hz input voltage, 24V 3.8 A output load, 25 °C (77 °F) ambient temperature, and after a 5 minutes run-in time.

The output is electronically protected against no-load, overload and short circuit. In case of a protection event, audible noise may occur. The output is designed to supply any kind of loads, including unlimited inductive loads. Capacitive loads should not be larger than 3300 μF with 3.8 A or 4200 μF with 1.9 A additional resistive load. At heavy overloads (when output voltage falls below 14V), the power supply delivers continuous output current for 20 ms. After this, the output is switched off for approx. 160ms 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.

The lifetime expectancy of the built-in electrolytic capacitors determines the lifetime expectancy of the power supply. Lifetime expectancy is specified in operational hours and is calculated according to the manufacturer specification of the capacitor. The manufacturer of the electrolytic capacitors only states a maximum life of up to 15 years (131,400 hr). Any number that exceeds this value is a calculated theoretical lifetime, which can be used to compare devices.

The MTBF value is a statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product. An MTBF value of, for example, 1,000,000 hr means that statistically one unit fails 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 50,000 hr or only for 100 hr. For these types of units, the Mean Time To Failure (MTTF) value is the same as the MTBF value.

The device complies with EN 61000-6-1, EN 61000-6-2, EN 61000-6-3, EN 61000-6-4, EN 61000-3-2 and EN 61000-3-3. The device complies with FCC Part 15 rules. Operation is subjected to following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Do not use this device on AC 100V mains with more than 2.9A load when the application is sensitive to short output voltage dips during mains interruptions even with a length shorter than 20ms.

Double or reinforced insulation insulates the output to the input. It is recommended that either the + pole or the – pole shall be connected to the protective earth system. This helps to avoid situations in which a load starts unexpectedly or cannot be switched off when unnoticed earth faults occur. The manufacturer conducts type and routine tests. Field tests may be conducted in the field using the appropriate test equipment, which applies the voltage with a slow ramp (2 s up and 2 s down).
