J3C-L20 25Nm Smart Electric Valve Actuator Type: J3C Model: L20 Available with actuator function: POWER OPEN - POWER CLOSE FAILSAFE MODULATING Feature rich J+J multi-voltage smart electric actuator with LED status light and function conversion kits. Overview The J3C-L20 low voltage electric valve actuator from the electric actuator manufacturer J+J offers an impressive list of standard features that include 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 feedback. The J3C Failsafe electric actuator is the same on-off J3C actuator but with a simple to install, user friendly ‘BSR’ failsafe function conversion kit. The J3C BSR failsafe actuator can be set to fail open or fail closed. The J3C Modulating electric actuator is the same on-off J3C electric actuator but this time with the quick and easy to install ‘DPS’ modulating function conversion kit. The J3C DPS modulating actuator can be controlled by either a 4-20mA or 010V control signal and provides feedback as standard. The LED light remains constantly lit if the actuator is able to respond to remote commands - if it can’t, it flashes. The sequence of the flashes indicates what the reason may be for it being unable to respond. J3C-L20 Electric Actuator Specifications Voltage range - automatic sensing Operating time (0-90 no load) Maximum break torque Maximum operating torque (run/ reseat) Duty rating Working angle Standard (on request) Motor switches 2 x SPDT micro switches End of travel confirmation (volt free) 2 x SPDT micro switches Ambient temperature range Electrical connecting plugs IP67 Weatherproof, UV protected, corrosion resistant plastic housing. LED light gives user continuous visual actuator status feedback - if the LED is flashing, there’s a problem! Many protective features as standard - such as over-torque and anti-condensation. Multi-voltage capable, automatically sensed Very user friendly and easy to install - all the electrical connections are external. J3C Consumption 24V AC At maximum torque 788mA (for power supply sizing x 3) 914mA (for power supply sizing x 3) Unique plug & play function conversion kits create FAILSAFE & MODULATING function from a standard on-off electric actuator. How this J3C electric 1/4 turn valve actuator works (on-off) Electrically operated valves are driven by an electric actuator containing a motor and gearbox. On receipt of a continuous voltage signal (not pulse) the motor runs and, via a gearbox in the electric actuator, rotates the valve stem. The motor stops at the desired position (usually 0 or 90 ) by an internal cam striking a micro-switch. The valve actuator remains in this position, with the voltage still applied continuously, until switched and a continuous voltage reversing signal (not pulse) is applied, which runs the motor in the opposite direction, reversing the rotation until a separate internal cam strikes a separate micro-switch and stop the motor.
