ZYG-H3D Solid State Relais und SSR und Relais

Specification Control Methods: ZYG-H3D DC-AC; ZYG-H3A AC-AC Load Current: 150A, 200A, 300A Load Voltage: 400VAC; 600VAC; 1200VAC Control Voltage: ZYG-H3D 3-32VDC; ZYG-H3A 90-280VAC Control current: DC: 10-25mA; AC: 12mA On Voltage: ≤1.8VAC Off Leakage Current: ≤5mA On-off Time: ≤10ms Dielectric Strength: 2500V/AC Insulation Resistance: 1000MΩ/500VDC Ambient Temperature: -30°C +75°C Cooling Condition: Load current 10-25A, heat sink required, above 40A needs to add fan. Mounting Methods: Bolt fixed The work instructions: LED Weight: 3.5kg Application circuit AC SSR Dimensions Wiring drawing Cautions 1. It requires stability either control signal or load power, and vibration range is less than 10%, or else the measures should be taken to avoid losing control and burning components or device; 2. Notice the polarities; avoid the wrong wiring to make the components permanent damaged; 3. Pay attention to environmental temperature. If the temperature is too low, it should preheat then start up it should increase the input current; If the condition temperature is too high, it should increase it must appropriately increase the input current; If the temperature is too high, cooling should be taken. If it works at high temperature conditions for a long time and different loads, the current amount should be increased (i.e., lowering the amount of SSR use, as follow on the table). 4. In multi-channel control (in particular, the manual mode), you must allow sufficient time for stagnation to prevent short circuits or damage equipment. 5 SSR should be installed away from the heat place, leaving enough space to cool. The contact should be surface smooth, clean and painted with thermal Grease. 6. When multiple SSR series and parallel use, the input voltage range of SSR should meet the technical requirements. 7. Be caution about the leakage current caused by the RC circuit internal SSR. 8. Over current and short circuit are the main reasons for causing permanent damage SSR. The methods are using fast over-current protection fuse and air switch. 9. The method of over voltage protection can be used outside the parallel varistor CMOV. CMOV size makes a decision of the power, while its thickness does the breakdown voltage value. 220V Series SSR can select the 620 470V varistor, 380V series SSR can select the 680V 820V varistor. 10. Resistive regulator is not suitable for occasions as follows: AC motor control; Require a full sine wave input condition; Require zero-output condition; The phase modulation waveform occasions as well as rectifier circuit; The place where produces radio frequency interference (load circuit in series an inductor, which reduces interference); The shield wire with a metal tube or shield; This product is non isolation type (input and output), it needs to notice the isolation of potentiometer and wire voltage, pay attention to safety during the installing.
