Digitally-Programmable 3.8kW DC Source

Astrodyne TDI now offers a digitally programmable ac-dc power supply that provides 3,800W of regulated power and can operate as either a current or voltage source up to 400V or 170A. The modular 3.8 kW Mercury-Flex is hot-swappable enabling maximum uptime. Designed for industrial applications that require a flexible, digitally-controlled industrial power supply with a universal voltage range of 90- to 264-Vac and a 50/60 Hz single-phase input, the Mercury-Flex is offered in a variety of adjustable dc output voltage range models including 0- to 28-Vdc, 0- to 56-Vdc, 0- to 85-Vdc, 0- to 125Vdc and 0- to 400-Vdc.

The advanced power conversion techniques of this reliable unit delivers efficiency up to 93% with a power factor of 0.97 or better, helping to lower energy requirements and heat dissipation. Its 14-Vdc auxiliary output is useful for powering miscellaneous user circuits.

By using the digital CAN-Bus or Ethernet interface, Mercury-Flex can be factory pre-set or field-programmed to operate in three different modes - constant voltage, constant current or constant power. The unit's digital read-back feature shows output voltage and current values, operating temperature and protection alarm status.

For applications that require higher power, the Mercury-Flex rectifiers can be easily connected to parallel current sharing groups through a four module shelf assembly. This enables designs of upwards to 228kW in a single universal 19" rack (30U).
