WR-XC and WR-MP SERIES

Single and dual output

• 2:1 input range

• WR-XC UL approve d

• Efficie ncy to 86%

• Is olate d outputs

• Six s ide d s hie ld

• Re mote on/off control on XC mode ls

• 100kHz s witching fre que ncy

• Two package s ize s available

The WR series DC/DC converters accept a wide input voltage range of 9-

18VDC, 18-36VDC or 36-72VDC. A 100kHz switching regulator produces

operating efficiencies up to 86% at full load and as high as 80% at light load. In

the case of duals, full power may be taken from either output. All models will

tolerate a short circuit between positive and negative outputs or between either

output and common indefinitely. Load regulation of ±1% , line regulation of

±0.2% , Pi input filtering and remote on/off control (XC package only) which can

be improvised as an undervoltage shutdown signal, are featured on all models.

Six-sided continuous EMI/RFI shielding is provided in both XC and MP

packages. The operating temperature range is –25°C to +71°C convection

cooled, with no derating required.
