Ametek / Elgar PDU 2000 Power Distribution Unit

The Ametek/Elgar PDU 2000 is an intelligent power distribution unit that manages and distributes AC power to multiple loads while serving as a control interface between a UPS, power conditioner, equipment loads, and host computer. Built on microcontroller-based architecture, It has individual control of eight NEMA 15A/115V receptacles with RS-232 serial communications for operational monitoring, alarm annunciation, and AC power status. The unit functions simultaneously as a serial data router, enabling computer-to-UPS communication through a single RS-232 port.
