Product Descriptions
The µMP series GEN II power supply is a configurable power supply with
market-leading density and efficiency. It features a very wide 85 to 264Vac input
voltage range and employs active power factor correction to minimize input
harmonic current distortion and to ensure compliance with the international
EN61000-3-2 standard – they have a power factor of 0.99 typical. The power
supplies also feature active AC inrush control, to automatically limit inrush
current at turn-on to 40A maximum.
The µMP series GEN II can deliver up to 1800 Watts maximum from the µMP16
case. The supply has a Low profile 1U size and has a power density of more
than 22.9 watts per cubic inch. When fed with a 180 to 264 Vac input, the µMP
Series GEN II can achieve a very high - 91% typical efficiency at full case load.

Absolute Maximum Ratings
Stress in excess of those listed in the “Absolute Maximum Ratings” may cause permanent damage to the power supply.
These are stress ratings only and functional operation of the unit is not implied at these or any other conditions above
those given in the operational sections of this TRN. Exposure to any absolute maximum rated condition for extended
periods may adversely affect the power supply’s reliability.

Note 1 - Derate each output 2.5% per degree from 50OC to 70OC. Cold start soak -20OC, allow 10 minutes warm-up before all outputs
are with in specification. Reverse air to 40OC Max due to fan derating.
Note 2 - Derate linear to 50% from 10000 - 30000 feet .

EMI Emissions
The µMP series has been designed to comply with the Class B limits of EMI requirements of EN55022 (FCC Part 15) and
CISPR 22 (EN55022) for emissions and relevant sections of EN61000 (IEC 61000) for immunity.
µMP16 is tested at 1200W at low line and >100Vac input, and 1800W at high line>200Vac input using resistive load.
Conducted Emissions
The applicable standard for conducted emissions is EN55022 (FCC Part 15). Conducted noise can appear as both
differential mode and common mode noise currents. Differential mode noise is measured between the two input lines, with
the major components occurring at the supply fundamental switching frequency and its harmonics. Common mode noise,
a contributor to both radiated emissions and input conducted emissions, is measured between the input lines and system
ground and can be broadband in nature.
The µMP16 power supplies have internal EMI filters to 2
ensure the convertors’ conducted EMI levels comply with

Radiated Emissions
Unlike conducted EMI, radiated EMI performance in a system environment may differ drastically from that in a stand-alone
power supply. The shielding effect provided by the system enclosure may bring the EMI level from Class A to Class B. It is
thus recommended that radiated EMI be evaluated in a system environment. The applicable standard is EN55022 Class B
(FCC Part 15). Testing ac-dc convertors as a stand-alone component to the exact requirements of EN55022 can be
difficult, because the standard calls for 1m leads to be attached to the input and outputs and aligned such as to maximize
the disturbance. In such a set-up, it is possible to form a perfect dipole antenna that very few ac-dc convertors could pass.
However, the standard also states that ‘an attempt should be made to maximize the disturbance consistent with the typical
application by varying the configuration of the test sample.

Operating Temperature
The µMP series power supplies will start and operate within stated specifications at an ambient temperature from -40 OC to
70 OC under all load conditions with internal fan. Derate each output 2.5% per degree from 50 OC to 70 OC. Cold start at
-20 OC, allow 10 min warm-up before all outputs are within specification. Reverse air to 40 OC max due to fan derating.
Forced Air Cooling
The µMP series power supplies include internal cooling fans as part of the power supply assembly to provide forced aircooling to maintain and control temperature of devices and ambient temperature in the power supply to appropriate levels.
There are 1 fan in µMP04 case and 2 fans in µMP10/16 case. The standard direction of airflow is from the fan side through
the power supply with exhaust on the output side of the power supply. Reverse airflow option is required with some
derating allowed. Allow 40 OC max ambient for reverse airflow.
Fan speed is controlled by thermal sensors in case and modules. In the event of a fan fault condition, the unit will protect
by latching off. AC input or Global Inhibit must be recycled to turn the unit back on after a fan fault condition.

Communication Bus Descriptions
I2C Bus Signals - J2
The µMP series power supply contains enhanced monitor and control functions implemented via the I2C bus. The µMP
series I2C functionality (PMBusTM and FRU data) can be accessed via the output connector control signals. The
communication bus is powered either by the internal 5V supply or from an external power source connected to the
StandBy Output (ie: accessing an unpowered power supply as long as the StandBy Output of another power supply
connected in parallel is on).
If units are connected in parallel or in redundant mode, the StandBy Outputs must be connected together in the system.
Otherwise, the I2C bus will not work properly when a unit is inserted into the system without the AC source connected.
Note:
PMBusTM functionality can be accessed only when the PSU is powered-up.
Guaranteed communication I2C speed is 100KHz.
SDA, SCL (I2C Data and Clock Signals) - (pins 2, 4)
These are pins for I2C communication and must be pulled-up in the system by 20K ohm resistor to 3.3V housekeeping; a
current source pull-up can also be used. If multiple units are used inside a system, the 3.3V housekeeping of each unit
must be connected in parallel in the system, otherwise, the SCL and SDA bus will be pulled low by the unit without AC
power.
A0, A1,A2 (I2C Address BIT 0, BIT1 Signals) - (pins 5,7,9)
Multiple configured µMP power supplies can be used in a single system, the power supplies can have parallel outputs or
providing multiple outputs. The µMP case has three address pins allowing the system to assign different addresses to
multiple PSUs used within the system. The I2C devices inside the µMP case are EEPROM to store FRU data and
microcontroller for PMBus. The table below listed all the possible addresses of the two I2C devices inside the PSU. Pull
the address pin to secondary return (COM) to set the address to “0” or High (or open) to set it the address to “1”.
I2C Bus Communication Interval
The interval between two consecutive I2C communications to the power supply should be at least 50ms to ensure proper
monitoring functionality.
I2C Bus Signal Integrity
The noise on the I2C bus (SDA, SCL lines) due to the power supply will be less than 500mV peak-to-peak. This noise
measurement should be made with an oscilloscope bandwidth limited to 100MHz. Measurements should be make at the
power supply output connector with 2.2K ohm resistors pulled up to StandBy Output and 20pf ceramic capacitors to
StandBy Output Return.
The noise on the address lines A0 and A1 will be less than 100mV peak-to-peak. This noise measurement should be
made at the power supply output connector.

I2C Clock Synchronization
The µMP power supply might apply clock stretching. An addressed slave power supply may hold the
clock line (SCL) low after receiving (or sending) a byte, indicating that it is not yet ready to process more data.
The system master that is communicating with the power supply will attempt to raise the clock to transfer the next bit, but
must verify that the clock line was actually raised. If the power supply is clock stretching, the clock line will still be low
(because the connections are open-drain).
The maximum clock low timeout for µMP is 25 millisecond.
The maximum transaction timeout condition for clock stretching for µMP is 100 millisecond.

Application Notes
Output Ripple and Noise Measurement
The setup outlined in the diagram below has been used for output voltage ripple and noise measurements on the µMP
Series. When measuring output ripple and noise, a scope jack in parallel with a 0.1uF ceramic chip capacitor, and a 10uF
aluminum electrolytic capacitor should be used. Oscilloscope should be set to 20MHz bandwidth for this measurement.
