SSR 10DA 25DA 40DA 50DA DC Control AC White Shell Single Phase Solid State Relay SSR 10DA

relay Choose a correct type Current of Equipment Ratio Current of SSRPS: The Ratio depend on the kind of your loading equipment. Resistive load :70%, Inductive load:20%,Capacitive load:10%. Resistive loads such as iodine tungsten lamp, incandescent lamp, resistance furnace, oven, electric water heater, etc Inductive loads such as electric fan, fluorescent lamp, high pressure sodium lamp, mercury lamp, metal halide lamp, motor, compressor, relay, AC contactor, transformer, etc Capacitive load, such as capacitor, power compensation cabinet Product Application: SSR series solid state relay adopts flame retardant engineering plastic shell, epoxy resin encapsulation, thread lead end wiring, with high structural strength, impact resistance, strong shock resistance, the driving current of the input terminal is small, which can be conveniently connected with computer terminals and various digital program controlled circuits. It is widely used in petrochemical instruments and equipment, food machinery, packaging machinery, textile machinery, numerical control machine tools, plastic machinery, fitness equipment, entertainment facilities and other automatic control fields. It is especially suitable for corrosive, humid, dustproof, explosion proof and other harsh environments, as well as frequent switching occasions. It is an updated substitute for AC contactor. Safety precautions: 1. When the load current is higher than 5A, the radiator must be used or installed on the metal baseplate with corresponding heat dissipation effect, and the heat dissipation baseplate of solid state relay should be coated with thermal conductive silicone grease between the heat dissipation baseplate and the installation surface, more than 40A plus fan strong cooling or water cooling. 2. When used in inductive load, high transient voltage and surge current are applied to the output terminal, which may lead to misleading on or damage of solid state relay, it is
