The PPI Spectral range of thyristor power controllers are designed for the control of heater batteries in HVAC systems and resisitive loads in electric furnaces.
All PPI Spectral controllers are self-powered and require a 0-10volt
input signal and are available in single and three-phase versions, the
units comply with current EMC and safety regulations are CE compliant
and built to BSEN 50178.
Designed to interface with a BMS control system
with an input signal of 0-10volts these Standard single and three phase
thyristor
controllers are available as DIN Rail; mounted units (12 & 18kW)
while larger free standing units are available from 54kW to 150kW
