Rugged, DC / DC Converter Delivers 200W In Railway And Other Harsh Environments
18 May 2007
Absopulse Electronics' BAP236R is a rugged DC / DC converter designed for railway and other heavy-duty applications. It utilises field-proven push-pull topology to deliver 200W at any DC-output voltage from 12V to 120Vdc (12Vdc output at reduced power). BAP236R can be powered from 24Vdc (17Vdc - 30Vdc range), 36Vdc (25Vdc - 45Vdc), 72Vdc (50Vdc - 90Vdc) or 110Vdc (77Vdc - 137Vdc), with other input voltages available on request. An optional redundancy diode allows for parallel connection to achieve higher output power or N+1 redundancy.
The BAP236R meets railway standards EN50155 and EN50121 and international safety approvals including EN60950. It is filtered to meet EN55022 Class B and EN50121-3-2 conducted and radiated EMI. The unit features full electronic protection and 80% efficiency at full load, depending on input voltage. An optional Form C output fail-alarm and remote shutdown are available.
This converter is convection / conduction-cooled via a base plate and rated for operation over 0°C to 50°C at full power without de-rating. It is housed in a low-profile 4.43in x 2.25in x 10in chassis, and it is fully ruggedised and conformal-coated to ensure immunity to shock, vibration, humidity, moisture, dust and insects.
Other converters in the BAP railway series include the 300W BAP 65R and 500W BAP 319R.
