Multi-voltage and solenoid-controlled interlock from Castell for UPS systems

Castell Safety International Ltd 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. Includes multi-voltage input: ranges from 24 V AC or DC to 220 V AC or DC
b. A monitored solenoid increases the safety performance rating
c. Aesthetics improved
d. Mounting dimensions retained as of the previous unit

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 energised. Removing the key switches the contacts to the 'off' state, and the key can then be used to open the access interlock.

Paul Marks, Castell's new product development director, explains: "Selecting the old KSUPS meant that customers had to first be sure of the signal voltage for the solenoid, which often led to delays in being able to place the order and selection errors. Removing these issues has been uppermost in our minds when we looked at how to develop the new KSUPS+. The solution we have delivered is multi-voltage. Together with the improved level of safety offered by the solenoid monitoring, and the enhanced look of the unit, we are sure the KSUPS+ will be a very successful product."
