H* = H2, H4 or H6 for A or C pinning options with 2kVDC, 4kVDC or 6kVDC isolation.
H* = H for B pinning option with 1.6kVDC isolation only.
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.

* add suffix "/A", "/A/X2", "/B"or "/C" for pinning options,
see next page and Isolation Restrictions.
* add suffix "/M" for metal case.
* add suffix "/SMD" for SMD package.
* add suffix "/CTRL" for control pin option
(A Pinning only)
* add suffix -R for Tape and Reel packaging
Isolation Restrictions
‘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.
Ordering Examples:
REC3-0512DRW/H2/A/CTRL= 2:1 input, 5V Vin, ±12V Vout, 2kVDC, pinout “A”, plastic case, control pin
REC3-4812SRWZ/H4/A/M = 4:1 input, 48V Vin, 12V Vout, 4kVDC, pinout “A”, metal case, no control pin
REC3-2412DRWZ/H/B = 4:1 input, 24V Vin, ±12V Vout, 1.6kVDC, pinout “B”, plastic case, no control pin
REC3-0505SRW/H6/C/SMD-R = 2:1 input, 5V Vin, 5V Vout, 6kVDC, SMD pinout “C”, plastic case,
no control pin, Tape and Reel packaging. Refer to Application Notes

Notes
Note 1: Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
Note 2: 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.
**Any data referred to in this datasheet are of indicative nature and
based on our practical experience only. For further details, please
