THE BEST MODULATION FOR THE LOAD GEFRAN solid state relays and power solid state relays are available with different types of power junction activation,
based on the type of load to be switched and on the level of accuracy required for the control. These functions
give the Gefran range high applicative flexibility." Zero crossing ", switching for excellent control of most resistive loads without creation of electromagnetic noise.
Control inputONOFFONV=voltage on loadtcTtt Supplied power = Installed power xTC/T V VExample with input 20% = 2V (IN 0-10V)or 4mA (IN 0-20mA) V = voltage on loadExample with input 50% = 5V (IN 0-10V)or 10mA (IN 0-20mA) V = voltage on loadV100msec40msec lt20msec lt Logic Control " Zero-crossing with optimized fast cycle ", switching for high-dynamic resistive loads (rapid heating systems),infrared heaters. This type of modulation transfers to the load a power proportional to an analog input signal, guaranteeing a variable cycle time optimized from 40msec to 400msec.
Analog Control Example with input 50%= 5V(IN 0-10) o 10mA (IN 0-20mA) Analog Control Soft Start Guidelines for product selection " Phase-angle ", switching for inductive loads such as transformers, infrared heaters, normally for very accurateadjustment and very rapid heating systems. This type of modulation transfers to the load a power proportional to an analog input signal, guaranteeing a cycle time of 20msec with slicing of single sinusoidal waves on the load. The soft-start power function is available.
