- OVP on all outputs WR-K Series devices are efficient, high power DC/DC converters with single, dual and triple outputs supplying 50 to 60 Watts. Their low profile 3.5 x 5.5 x 0.91 inch package provides a power density of 3.4 Watts per cubic inch. Efficiencies range from 78% to 84%. These converters feature unique dual power stages utilising forward converters with MOSFET switching at 100kHz. A Pi network input filter is also included. High efficiency is virtually constant down to 30% output loading. Other features include output short circuit protection, overvoltage protection, remote sensing of primary output, input surge protection and remote on/off control. The 2:1 input voltage ranges are 9 to 18VDC, 18 to 36VDC and 36 to 72VDC. Typical applications for WR-K Series power supplies include telecoms, distributed power systems and industrial automation. SPECIFICATION All specifications are typical at nominal input, full load at 25 ° C unless otherwise stated PAGE 1

2 To order the optional heatsink on the PC mount model, add the suffix '-1'
to the model number e.g. WR24D05-12/55K-1. To order the chassis mount version with barrier terminal strip, add the suffix '-3' to the model number e.g. WR24D05-12/55K-3. Limit one option per unit. 3 No minimum load required for operation. 4 5V outputs clamped at 6.8V; 12V or 15V outputs clamped at 18V.
5 Can compensate for up to 1V drop between converter and load (all single-
output versions, and output 1 of dual-output and triple-output versions). 6 Remote sense is provided on all singles, and output #1 of duals and triples. If remote sense is not being utilised on single output units, for normal operation pin 14 should be jumpered to pin 10 and pin 12 to pin 8. For dual output units, if remote sense is not being utilised, connect pin 11 to pin 10 and pin 8 to pin 9. Remote sense can compensate up to 1V drop between converter and load.
7 Single output models: to trim up connect pin 13 to pin 12 through a 10k Ω
resistor; to trim down, connect pin 13 to pin 14 through a 10k Ω resistor. 8 Dual output models: the trim facility is provided only for output #2. To trim up connect pin 13 to pin 12 through a 10k Ω resistor; to trim down connect pin 13 to pin 14 through a 10k Ω resistor. 9 In many cases, the isolation specification may be upgraded. 10 MTBF figures are based on actual product performance.
11 The two-stage design of the WR-K Series provides isolation between
outputs which means outputs can be referenced as either positive or negative. On dual output models, the outputs can be referenced as positive or negative. On triple output models. The 5V main output is isolated from the auxiliary outputs. No load sharing is possible.
12 For reverse input voltage protection, connect an external fuse in series with
the input.
13 Fixed frequency design provides for easier input filtering and better noise
performance.
14 Standard specifications are conservative and can be optimised for specific
applications. In particular, converter start-up at lower than specified temperature, wider input voltage range, and, output voltage adjustment are all relatively simple modifications to the standard product.
