Liquid cooling for configurable 20kW power supply

Advanced Energy has added a liquid cooling option to its high-power power supplies for stable and accurate high resolution power delivery up to 120kW in critical applications.

The iHP Liquid family from Advanced Energy is a digitally configurable power system providing up to 20 kW of power in a 4U rack form factor. The liquid cooling means the unit is a fully sealed unit for environments where fan-based air cooling is not desirable such as industrial, lighting, horticulture, medical and semiconductor applications.

It can be configured to either a single output or up to eight outputs upon request. A total of ten output modules are available that can be programmed to operate in constant voltage or constant current modes. Each module is highly adjustable, and flexibility is further enhanced with the ability to combine modules in series or parallel to increase voltage or current as necessary. As a result, the iHP can deliver currents as high as 1600 A or voltages up to 1000 V.

Offered with 3-phase, 4-wire (Wye or Delta) input, the iHP contains active power factor correction (PFC) for very low THD and power factor that exceeds 0.98 at full load. By combining six 4U iHPs operating in parallel, a completed rack system of iHPs can deliver a total of up to 120 kW of power at the high efficiencies of up to 94.8% (480 VAC input, 50% load).

“Managing operating temperatures is crucial to delivering reliable operation while also controlling running costs,” said Chris Jones, Director, Technical Marketing at Advanced Energy. “Built upon our well-established configurable technology, the new iHP Liquid delivers up to 20 kW of power in a compact 4U rack form factor within a fully sealed outer box, making it ideal for locations where airborne dirt or moisture may be present. The iHP series comes with a wide range of available output power modules, accessories and software, enabling this solution to be quickly and easily tailored to almost any application.”

Control of both current and voltage can be achieved via a simple analog voltage (0-5 V or 0-10 V) or more sophisticated digital control is available with the optional PowerPro connect module. This versatile device provides a standard Ethernet interface via the Internet to a cloud- and dashboard-based user-configurable GUI. Available communication protocols include Digital Ethernet UDP, RS485, MODBUS, CAN or Ethernet TCP-IP.

The iHP Liquid offers a programmable slew rate and is compliant with EN61000-4-x (IEC1000-4-x) and EN55011 for EMC. Safety approvals include UL/CSA/EN 62368-1 and five of the output modules offer 2x MOOP / MOPP.
