General Description
This PMU panel mount power supply, with integrated DC UPS function, prevents end-product downtime for the customer in the event
of failure/disruption or unexpected loss of input AC power. The power supply will switch to battery operation (batteries not included)
without interruption to increase the operational reliability of the critical mission. The TTL compatible monitoring signals for AC OK, DC
OK and Battery Low will alert the user in the event of a failure. This convection-cooled single phase power supply has a wide operating
temperature range from -20C to + 70C and is suitable for security system, access control, automatic doors, alarm system, and other
similar products. In addition to having overvoltage, overload, over temperature, deep battery discharge, and reverse battery polarity
protections on the main output, there are also short circuit and overload protections when operating in the buffering (battery discharging)
mode. The PMU design meets worldwide safety approvals, certified to Class B radiated and conducted emission requirements, and is
also available in an L Frame platform for different application needs.

1) For power de-rating from < 0C to -20C, and 50C to 70C, and power de-rating at input voltage, see power de-rating on page 11.
2) If a battery is not connected to B+ and B-, when PMU is turned on, a voltage cannot be seen at these terminals.
3) The maximum combined output power from V1 and B+ is 151W at 180-264Vac input but the output power is reduced to 136W at 90-132Vac input
For example;
151W; V1: 27.6V/4A (110.4W), B+: 27.1V/1.5A (40.6) or V1: 27.6V/5.5A (151W), B+: 27.1V/0A (0W).
136W; V1: 27.6V/3.45A (95.2W), B+: 27.1V/1.5A (40.6) or V1: 27.6V/4.9A (136W), B+: 27.1V/0A (0W).
Battery charging current at B+ output can be adjusted according to output current range in parentheses by battery charging current adjustment potentiometer.
Load range in parentheses and rated current outside parentheses.
4) PARD is measured with an AC coupling mode, 5cm wires, and in parallel with 0.1F ceramic capacitor & 47F electrolytic capacitor.
All parameters are specified at 25C ambient and AC input unless otherwise indicated.
