The J3C-S20 multi-voltage smart electric valve actuator from the European electric actuator manufacturer J+J offers an impressive list of standard features that include 24-240V multi-voltage capability, protection against damage from over-torque or condensation, safety features, the ability to have it’s standard on-off function changed with user friendly plug & play conversion kits, and a highly visible LED light to offer users continual actuator operational status feed back. The innovation in the J3C S Type of 24-240V AC or DC multi-voltage capability with automatic voltage sensing has a patent pending. The multi-colour LED light remains constantly lit if the actuator is functional and able to respond to remote commands - if it is unable to, the LED flashes. The sequence of the flashes indicates the possible reason. This user friendly contin uous visual status feedback LED gives the user at-a-glance actuator status, and assists in fault diagnosis. For 12V applications, a small adapter PCB can be installed which restricts the supply voltage to 12V AC or DC only.
