4-20mA input control Single-phase isolated AC solid-state voltage regulator module High-quality and economical

If need 0-10V or 0-5V control,please remark when place order.

(I) Overview?1. Longke's small single-phase AC solid-state voltage regulator module integrates current control circuit, photoelectric isolation circuit, phase-shift trigger circuit, one-way or two-way thyristor, RC resistance-capacitance absorption circuit, which is equal to one, and the current signal Under the action of the control circuit, the conduction angle of the thyristor is automatically adjusted to change the voltage on the load, thereby adjusting the output power.?2. The voltage regulator module is suitable for loads such as heating wires, IR far infrared rays, UV lamps, and transformer coils.?3. The output voltage of the voltage regulator can be steplessly modulated, with good adjustment linearity, small size, and particularly simple and convenient wiring.?4. The voltage regulator takes power directly from the 4-20mA control signal, without any external AC or DC power supply.?5. The voltage regulator adopts SMT process, DCB ceramic substrate, stable performance and high reliability.?6. The voltage regulator has LED working instructions. There is voltage output when the indicator light is always on, and it is abnormal when the indicator light is flashing.?7. The input control terminal and the strong current main circuit are fully isolated (isolation) design, and the insulation medium withstand voltage is greater than 2000 Vac.?(II) The load output current grade and model of the small solid-state voltage regulator module are as follows:
The above data takes the common 22 load or 380 load as an example.1. Selection method: first calculate the load current at full voltage, and then multiply the load type by the margin coefficient. The resistive load coefficient is 3 times; the inductive load coefficient is 5 times.Example: 2208KW resistive load. 8KW/220V3 times = choose 120A specification, LSA-H2P120R2. Resistive load refers to: incandescent lamp, resistance wire, oven, heating rod.Inductive loads refer to coils, fan motors, and water pump motors.3. Loads that cannot be used: household appliances (such as televisions, computers), electrical appliances with switching power supplies, and no load.?
