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.

NOTES

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.
