DESCRIPTION

The WPC10 series is a family of DC/DC converters

that offer regulated outputs over an input voltage

range 18 - 36V and over a wide speciﬁcation case

temperature range of -40°C to +100°C.

The 350kHz switching frequency and forward

converter topology provide optimum performance

in a space-saving package. The design uses

all surface mounted components, including

magnetics, to provide enhanced reliability.

All models will operate under very low load

conditions, although the minimum load is required

to guarantee full parametric functionality. A metal

package is utilized for decreased radiated noise.

The product range has been recognised by Under-

writers Laboratory (UL) to UL 1950 for operational

insulation, ﬁle number E179522 applies.

TECHNICAL NOTES

ISOLATION VOLTAGE

‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test voltage,

applied for a speciﬁed time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.

Murata Power Solutions WPC10 series of dc/dc converters are all 100% production tested at their stated isolation voltage. This is 1500V Vpk for 10 seconds.

A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”

The WPC10 series has been recognized by Underwriters Laboratory, both input and output should normally be maintained within SELV limits i.e. less than 42.4V peak, or 60VDC.

The isolation test voltage represents a measure of immunity to transient voltages and the part should never be used as an element of a safety isolation system. The part could be

expected to function correctly with several hundred volts offset applied continuously across the isolation barrier; but then the circuitry on both sides of the barrier must be regarded

as operating at an unsafe voltage and further isolation/insulation systems must form a barrier between these circuits and any user-accessible circuitry according to safety standard

requirements.

REPEATED HIGH-VOLTAGE ISOLATION TESTING

It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on materi-

als, construction and environment. While manufactured parts can withstand several times the stated test voltage, the isolation capability does depend on the wire insulation. Any

material, including this enamel (typically polyurethane) is susceptible to eventual chemical degradation when subject to very high applied voltages thus implying that the number of

tests should be strictly limited. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be reduced by 20% from

speciﬁed test voltage.

FUSING

The WPC10 series DC/DC converter may be optionally fused with a 2A fuse. The input must be SELV or TNV according to EN60950/IEC950. UL recognition was obtained without an

input fuse.

RoHS COMPLIANCE INFORMATION

This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260ºC for 10 seconds. The pin termination ﬁnish

on this product series is UNS C36000 brass plated with matte tin 100 micro-inches min., over nickel, 40-80 micro-inches. The series is backward

compatible with Sn/Pb soldering systems. For further information, please visit www.murata-ps.com/rohs
