Absopulse Electronics’ HBL 600 Series is an open-frame, heavy duty AC/DC switching power supply that uses a field-proven full-bridge topology to deliver up to 600W, depending on the output configuration required. The standard version is rated for a single dc-output voltage of 24V, 28V, 48V, 56V or 125V, and it can be operated from 115Vac/230Vac line voltage. A 250Vdc input version, (190 to 370V range), is also available. Other inputs/outputs are available on request. An optional built-in redundancy diode allows for parallel and N+1 operation.
This low-profile, open-frame power supply is 1.5″ high and is cooled by conduction via baseplate to a heatsinking surface and by natural convection. It is rated for operation over 0ºC to +50ºC 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. The HBL 600 is filtered to meet EN55022 Class A EMI as a minimum and it meets international safety approvals including EN60950 and related UL and CSA standards.
Customized and fan-cooled versions with increased output power are also available.
