Slave Serie Mono-phase

The VRMS electronic controller is used to adjust proportionally and continuously the speed of voltage adjustable fans, through a particular software which guarantees the best performance in regulation. They function as a simple voltage regulator whose command signal comes from a remote control or from a potentiometer.FAE produces a version for pwm signal command and a version for 0..10V= command signal. 

The VRMS regulators are robust because they are enclosed in an aluminum case. They are easy to use because they can be hooked on a rail (Omega RAIL DIN/EN 50022) and fast to wire because they have spring-loaded terminals and output power terminals for direct connection to several loads.
They are an excellent solution for reduced sizes and lowcost applications.


The standard version presents the following features:
- Mono-phase power supply 230Vac 50-60Hz,
- Command input 0..10V, potentiometer 10kohm (input impedance10kohm) or pwm (input impedance 150ohm),
- Dip switches with 7 positions to select one of the following voltages/speeds on the load: 170V-180V-190V-200V-210V-220V-230V,
- Dip switch for activation of the speed up function at the start,
- Auxiliary output (terminal +10V) to supply a potentiometer,
- Protections: Class II for input commands (4kV), class I for the accessible parts; Overvoltage protection Class II.
- Working temperature: -25T50°C, storage temperature -40T80°C,
- Protection grade : metallic IP20 case, pollution grade 3
- Standard norms applied: EN60730-1, EN61800-6-3
