Absopulse Announces New Heavy-duty 1,600W Power Supply For 1U Applications

Absopulse Electronics announced its HBL 1K6 series – a heavy duty, modular ac-dc switching power supply system. It uses a field-proven full-bridge topology to deliver up to 1600W, depending on output voltage requirements. This system is housed in a ruggedly constructed 1U x 19" rack-mount chassis and is suitable for industrial plants, air-traffic control systems, power utilities, radio communication and other critical applications.

The standard version of the HBL 1K6 is rated for any single dc-output voltage from 12Vdc to 150Vdc. It can be operated from a 230 or 115Vac line voltage. A 250Vdc input (190 to 370V range) is also possible. Other input/output configurations are available on request. An optional built-in redundancy diode allows for parallel and N+1 operation.

This low-profile unit is fan-cooled and rated for operation over 0 to 50°C at full load without de-rating, with wider temperature ranges available on request. Other options include additional ruggedizing and conformal coating for immunity to extreme levels of to shock, vibration and humidity. The unit features full electronic protection and 80% efficiency at full load, depending on input/output voltage configuration. The HBL 1K6 is filtered to meet EN55022 Class A EMI as a minimum and meets international safety approvals including EN60950 and related UL and CSA standards.

Standard versions of the HBL 1K6 are priced in a US$1,058 range in quantities of 100.
