Delta Electronics PJU-60W Power Supply Units
Delta Electronics PJU-60W Power Supply Units are Open Frame Un-interruptable Power Supplies (UPS), making them ideal for security applications. The PJU-60W PSU will automatically switch to battery mode operation to prevent system down-time in the event of power disruption or unexpected loss of ac input power. The PJU-60W PSU is offered in two variants. The PJU-13V60WCBA features a 13.8V 3.5A output, and is designed to work with a 12V sealed lead-acid battery. The PJU-27V60WCBA features a 27.6V 1.4A output and is designed to work with a 24V sealed lead-acid battery.
The main output channel and battery channel of the PJU-60W PSU will operate in CC-CV mode to maintain voltage regulation of main output channel while charging the external battery, and to prevent damaging deep discharge, the battery is disconnected if drained below 9V or 18V depending on version. Delta Electronics PJU-60W PSUs also include safety features such as reverse polarity battery connection, over-voltage, over-current, over-temperature, and short-circuit.
