Castell’s Multi-voltage Solenoid-controlled interlock for UPS System Safety

KSUPS+ improves delivery times and safety rating
Chicago, Illinois (April 27, 2012) – Industrial safety specialist Castell has launched a new multi-voltage 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 24 V AC or DC to 220 V AC or DC.

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

Castell has also reviewed improved the operational efficiency of the KSUPS+, with clear indication of where the safety component is located on a switchgear panel. The KSUPS+ retains the same mounting dimensions as the previous unit for easy retrofitting.

Inserting and turning the key operates four pole switch contacts and allows the system to run. The key remains trapped and can only be released when a signal is received by the device and the solenoid is energized. Removing the key switches the contacts to the ‘off’ state, and the key can then be used to open the access interlock.
