Overview:

ZKG, ZKD, SCR series intelligent voltage regulators are used with SCRs to accurately adjust the voltage on the load. The meter adopts a phase-shift trigger method for the SCR to achieve the purpose of continuous voltage regulation. Because this meter has negative voltage feedback Function, the fluctuation of the power grid has less influence on the output voltage.

This voltage regulator adopts international advanced special control microprocessor, RISC instruction set design, two-color LED digital display, excellent control performance, high cost performance, compared with traditional pointer regulators, it has high precision, high shock resistance and good reliability. , Strong anti-interference ability, small size, light weight, clear reading, no parallax and other unique advantages.

It can be widely used in blow molding, blister molding, mold heating, packaging machinery and other mechanical equipment.

Installation:
1. Select the appropriate thyristor according to the work needs. For 220VAC lines, a thyristor with a withstand voltage greater than 600V should be selected. The rated current of the SCR is more than twice the actual maximum working current. At the same time, pay attention that the peak current is within the limit value of the SCR.
2. Equip the SCR with enough radiator to ensure that the operating temperature of the SCR is below 80°C, and use air cooling to dissipate heat if necessary.
3. Wire correctly according to the wiring diagram. If you need to change the wiring diagram due to actual needs, please contact us.

Instructions for use:
1. "P" key is the standby key. When the controller is in the standby state, the SCR has no output, and the controller displays "OFF" or "P", but the controller itself is still running and in the standby state.
2. "∧" and "∨" keys are the set value plus and minus keys. When the controller is working, press "∧" or "∨" key to modify the set value.

Precautions:
1. This controller is only suitable for resistive loads, not for inductive (capacitive) loads, such as transformers, induction furnaces, etc.
2. During use, if the measured value flickers, please check the SCR and whether the load is damaged.
3. This controller can only be used with triacs.
4. If you need to use SCR module, single-phase SCR, please specify when ordering.
5. This controller is guaranteed for 12 months.
