Industrial safety specialist Castell,
currently celebrating its 90th
birthday, has launched a new multivoltage
interlock primarily for use
with uninterruptible power supply
(UPS) systems. The KSUPS+ is a
solenoid-controlled trapped key
interlock that only permits access to
a UPS system once the system has
been put into a safe condition.

The KSUPS+ features a number of
design improvements, including
multi-voltage input. Having a wide
voltage input range means that a
single device now replaces eight
previous devices; the input voltage
for the KSUPS+ ranges from 24V AC
or DC to 220V AC or DC.

As a safety device, the integrity of
the KSUPS+ is vital. A monitored
solenoid increases the performance
rating of the KSUPS+, ensuring a
higher level of protection for personnel
while working on UPS systems.

Castell has also reviewed the
aesthetics of the device.
