DESCRIPTION
The MPQ series of single output DC/DC converters provides up to 125 watts in a quarter-brick
package. The MPQ series is well suited for telecom and datacom applications where high
efficiencies are required. Some features include active high or active low remote on/off, fixed
switching frequency, low output ripple, and 10% output trim. These converters also have
over voltage, short circuit, over current, and over temperature protection. These high density,
low voltage input, quarter-brick converters offer great performance and high reliability at a
very competitive price.
Size (Open Frame):
2.28 x 1.45 x 0.43 inches

1. All 24 VDC input models must have a case. 48 VDC input models can either be open frame (no suffix) or have a case (“C” suffix). Both 24Vin and 48Vin
models are heatsink compatible.
2. A heatsink can be applied for an extended temperature range. For heatsink, add the suffix “HS” to the model number.
3. Remote ON/OFF is primary referenced. Active High is standard; for Active Low add the suffix “R” to the model number.
4 Al DC/DC converters should be externally fused on the input side. Please consult factory for more information.
