This unit is perfect for use in applications where it crucial that uninterrupted use of equipment is maintained in the event of a power cut. The batteries will automatically be recharged by the power supply and the unit will switch back to AC operation when the mains supply is restored
These battery back up power supplies feature AC OK and battery low alarms which can be driven by any external DC voltage from 4 volts up to 50 volts with a 30mA maximum load. If the main power source is interrupted the PAXB60 switches to battery backup mode and a TTL signal will be sent out to a monitoring unit to warn of impending equipment failure. If the battery voltage goes down to 11V (for 12V battery bank) or 22V (for 24V battery bank), another TTL alarm signal will be sent out to warn of the battery low situation. The battery backup loop will be cut off when the battery voltage goes down to 10.5V or 21V to prevent batteries from over-discharging.
The units also feature free air convection cooling, short circuit, overload and over voltage protection. Battery polarity protection (by fuse) and battery low cut-off for the battery side in a small 4” x 2” compact design . The PowerPax battery back up power supplies operate at 84% efficiency and carry UL, CUL, TUV, CE and CB safety approvals.
PowerPax also manufacture custom battery back up power supplies on request with no minimum order quantity and depending on the complexity of design, often no design charge either. Please contact PowerPax for further details.
