The ZAD series of single output DC/DC converter provides up to 200W in an extremely compact package over a wide range of
input and output variations. Available in one and the same package size, the high efficiency ZAD delivers a convection cooled
200W in a 19", 3U or open frame chassis. The ZAD series comes with a host of features including high power density, optimized
design topology depending on the relation of input and output voltage, free convection cooling, efficiency up to 95%, high
ambient and storage temperature range and excellent protection of input, output and over temperature, external ON/OFF,
parallel and n+1 redundant operation for higher power application. Nominal output voltages with ±5% adjustment range and user
defined set-points. ZAD carries safety certificates as per EN60950 for industrial application as well as being compliant with all
relevant EMC emission and immunity standards. The product can also be conformal coated and ruggedised for use in harsh
environments. With convection cooled power capability of 200W the ZAD is ideal for use in a wide range of applications: industrial,
automotive and rail, automation, energy and safety.
