General Description

1.1

Intended Applications

The 

37&

110BA-2 is a high quality, rugged, 400Hz IN 60Hz OUT, 1kW / 2KVA, 19” rack-mounted 

8Q

interruptible Power Source (UPS).  In addition to full compliance with all the requirements of MIL-

STD-1399 (Section 300), the 

37&

110BA-2 is specifically designed to meet the harsh military ship

ERDUG

environment. The high reliability and ruggedness of the 

37&

110BA-2 make it an excellent 

FKRLFHQRW

only for military shipboard applications, but for tactical shore-based applications as well.

1.2

Functional Overview

The 

37&

110BA-2 consists of two main sections:  Power Conditioner and UPS (see Fig. 1).

The Power Conditioner is a 400Hz isolation transformer (with RFI filters and spike absorbers).

In addition to 115Vac to the UPS section, the isolation transformer provides a low voltage for the

24Vdc contactor supply. When AC input drops, the 24Vdc is provided from battery power. The

Power Conditioner contains internal fuses on its input. These internal fuses are intended only as a

safety feature in case of an internal failure.

The UPS is composed of a high power factor AC-DC Converter, a Removable Battery Pack, a

Battery Charger, a DC-AC Inverter and a microcontroller-based Control Circuit.

The AC-DC Converter is a high frequency switching converter that provides 320VDC to the DC-AC

inverter.  The AC-DC converter draws clean sine input current waveform and does not induce

electrical noise into the input lines.

The Removable Battery Pack contains the energy source used by the UPS to provide power during

AC input failures.  The Battery Pack includes eight 12V / 5AH lead-acid, sealed, maintenance-free

type cells.  It provides 10 minutes of full rated output power.  The Battery Pack is not a serviceable

item. It cannot be disassembled, and can only be replaced as a single unit.

The Battery Charger is a high frequency, voltage-regulated and current-limited DC to DC converter.

It is powered from the 320VDC output of the AC-DC Input Converter and provides temperature-

compensated float charge to the Battery Pack.

The DC-AC Inverter is a high frequency inverter that generates a clean sine-shape 60Hz, 115VAC

voltage from the 320VDC output of the AC to DC Input Section.  The DC-AC Inverter is current-

limited and has an overload protection circuit that turns it off (latched) after a delay from the time

the load exceeds 120%.  The delay depends upon the overload level.

The Control Circuit is a microcontroller-based circuit that provides monitoring of the unit’s status

(battery charge, load level, input and output levels, etc.) and supports communications and front

panel status indicators.
