Rugged uninterruptible power supply (UPS) for aerospace, defense, and battery charging introduced by SynQor

UPS can draw power from AC input voltages and frequencies, or from a 28-volt DC power source and deliver three different isolated DC output voltages.

BOXBOROUGH, Mass. – SynQor Inc. in Boxborough, Mass., is introducing the DC3 full power, high-voltage DC adjustable-output field-grade isolated uninterruptible power supply (UPS) for military and aerospace applications.

The DC3 1250-Watt high-voltage DC adjustable output can deliver any output voltage between 25 volts DC and 325 volts DC; at full power it can deliver between 210 and 325 volts DC. The output voltage and current limit are user configurable.

The rugged DC3 output of several units can be paralleled or configured in a N+M redundant configuration for increased output power. The UPS also can be configured to deliver simultaneously to the high-voltage DC output a 24-volt DC or 28-volt DC through its DC2 port and either 12, 15, 24, 28, 40, or 50 volts DC at 500 Watts through its DC1 port.

The UPS can draw power from a wide range of AC input voltages and frequencies, or from a 28-volt DC power source and deliver as many as three different isolated DC output voltages.

Battery charging applications also are possible with the current limit feature. It is designed to withstand harsh and extreme electrical, shock/vibration and environmental conditions. Providing the power backup is a small sealed lithium polymer battery pack.

This UPS also includes features that simplify its operation such as the SNMP Ethernet base module that allows real time remote system monitoring with trap/email features that warn users and monitors consoles for important system events.

Another feature allows a 47 to 800 Hz dynamic input frequency range of operation for varying frequency input AC applications. These UPS models have a droop share option in the DC2 port which allows for load sharing and redundant (N+M) configurations between several UPS units at low output voltages.
