The PWS310 Series of power supplies provides 12, 24, 32 or 48 Volts DC at 300 Watts of continuous power from a 110 or 220 Volt AC source.
Analytic Systems' power supplies use Switchmode technology with powerful IGBT switching transistors for reliability and efficiency with minimum size. Circuit innovations reduce output ripple to levels previously available only from bulky and inefficient linear power supplies. Reliability features include an input fuse, thermal shutdown, current limiting and output short circuit protection with automatic recovery. An output over-voltage crowbar circuit protects any powered devices from excessive voltage in the event of a failure of the unit.
The newly updated single-board PWS310 is ultra-quiet and features the latest generation of current mode PWM control. Extra features include adjustable output voltage audible and visual indicators for low input voltage, low output voltage, over temperature, overload and output on. Either 110 or 220 VAC input is available. The PWS310 also features a four contact output terminal (two positive and two negative contacts) for easy connection of devices to the supply.
