HGP Series Solid State Relay
Product Detailed
Output current type: 3 4 5
Operating voltage range:2:28 280VAC 3:48 480VAC
Max. Surge current-Non repetitive (10ms):80Apk...
Application:
PRECAUTIONS: When controlling AC inductive load, the SSR may be damaged by the high transient voltage and surge current added on the output, so some special clamping devices to control voltage, such as zener diode, varistor . When controlling DC inductive load, such as solenoid, motor starter, etc, a continuous current circuit should be used to control the reverse electric motor force. Generally speaking, a simple way is to parallel the load with a diode inversely, but thus will affect the release time of inductive load. A better way is to series a diode with a zener diode inversely or to series a diode with a resistance . When controlling a small current(close to Min. load current),a dummy resistance should be paralleled to reduce the rest voltage produced by the surge current on the output. When a jointing type relay is mounted, the temperature should be controlled under 260 centigrade degrees and the time will be limited within 5second. To avoid the temperature exceeding the allowance, heatsink efficiency and the mounting position should be regarded, suitable space will be left when two or more SSR are mounted .
