Description
Besides the standard isolation of 2kVDC, this series offers options of 4kVDC (= "/H4") or 6kVDC
(="/H6") making it suitable for medical applications and other sophisticated industrial applica-
tions. Packaging can be either DIP-24 plastic or 5-side-shielded DIP24 metal case (=option
"/M") as well as SMD pinning (= option "/SMD"). For all the above variants, 2 industry-standard
pinouts (= option "/A" or "/C") are available, and B pinning is available with 1.6kVDC isolation.
Remote on/off control is possible with the /CTRL option (A pinning only). The converters can
deliver 140% rated power for short periods of time to cope with applications with large
capacitive loads or high start up currents.

‘B” Pinning is restricted to 1.6kV isolation due
to the closeness of the input and output pins.
If the options "/M" for metal case and "/SMD"
for SMD pinout are combined, the maximum
allowed isolation voltage is 2kVDC because of
the shorter distances between pins and the
metal case.
DIP-24 through-hole case and SMD-plastic
case are not affected and offer the full isolation
barriers of 2kV through to 6kVDC.

Notes
Note 1:
Note 2:
Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
The REC3-RW series requires a minimum of 10% load on the output to maintain specified regulation. Operating under no-load
conditions will not damage these devices; however, they may not meet all listed specifications.
