The PALS Series consists of 400 and 600 watt ac-dc power supplies designed specifically for use in power-over-
ethernet applications. The supplies have dual outputs of 48 and 12 volts which provide LAN port and internal system
power. A 500 mA standby output facilitates I2C interface operations. The units are fully-enclosed, have 1500 VAC
(2250 VDC) output isolation, and comply to IEEE802.3AF.
The PALS Series provides excellent protection against input voltage transients. Supply outputs are fully floating,
meaning that users can use them for either positive or negative polarity needs.
Output voltage terminals and interface access is through a hot-swap connector at the rear of the supply. The AC input
fans, handle, and LED indicator lights are located on the front panel of the supply. Airflow is from the front through the
rear. Alarm, monitoring, and control signals are floating from the rear output and can be referenced.
The PALS Series meets international safety requirements and is CE Marked to the Low Voltage Directive.
