The PSK/PSS Series of positive switching regulators is de –
signed as power supplies for electronic systems, where no
input-to-output isolation is required. Their major advantages in-
clude a high level of efficiency, high reliability, low output ripple,
and excellent dynamic response. Models with input voltages
up to 144 V are specially designed for secondary switched and
battery-driven mobile applications. The converters are suitable
for railway applications according to EN 50155 and EN 50121.
Two types of housing are available allowing operation up to
71 °C. They are designed for insertion into a 19″ DIN-rack or
for chassis mounting. Replacing the heat sink by an optional
cooling plate, allows chassis or wall mounting on top of a metal
surface, acting as heat sink
