Perfect backup power solution
Designed for critical base stations and repeater sites that must remain online, the Newmar Power Pac Power Supply will keep your essential devices running in the event of an AC power failure. The Power Pac's highly regulated, low ripple 10 amp output powers radios and at the same time it float charges one or two built-in 7 amp/hour back-up batteries. These are kept at peak charge during the normal functioning of the unit when AC is being supplied. In the event of a loss of AC power, the internal batteries automatically take over to power the communications equipment, providing a true uninterruptible DC source.
Regulated Noise-free Output
The Power Pac features a highly regulated, low ripple output (see specifications) to power radios and other sensitive communications equipment without causing RF or audio interference.
Battery Back-up
A 7 amp-hour battery is built into the unit to provide up to 20 amps of emergency transmit power. It is charged automatically by the output of the Power Pac during normal operation.
Battery and Input/Output Status Indicators
The operator is kept informed of all important functions such as AC input, DC output and battery status with front-panel indicator lights and a warning buzzer.
Automatic Low Battery Disconnect
The battery is protected against damage from extreme discharge by a circuit which will automatically disconnect the load when output voltage reaches 10.3 VDC.
Over-Voltage Protection
The radio being powered is protected against damage from any condition which might cause excessive output voltage by an over-voltage protection (OVP) circuit.
Current Limit Protection
The Power Pac is protected against damage due to overloads or shorts on the output by an automatic current limiting circuit.
Fusing
AC input and internal and external batteries are fused for additional protection against high current conditions.
Automatic Thermal Shutdown
The Power Pac is protected against overheating (when duty ratings are exceeded) by an automatic thermal shutdown circuit. When a safe operating temperature is restored, the Power Pac automatically returns to service.
