TDK-Lambda TPS4500 AC-DC Power Supply

TDK-Lambda TPS4500 AC-DC Power Supply offers power levels up to 4600W in a 2U high package with a 3-phase 360VAC to 528VAC supply input. This power supply can be used as a single or dual output, sharing the load in any proportion up to the rated output. The TPS4500 AC-DC power supply can be connected in series or parallel to increase the output voltage or power. This power supply features voltage and current programming (CV/CC operation), remote on/off, a standby supply, and PMBus™ communication. The TPS4500 AC-DC power supply is designed to meet MIL-STD-810H vibration and shock. Typical applications include industrial, test and measurement, communications, broadcast, and COTS.
