ELECTRICAL PARAMETERS

Industrial DC–AC switching.

Control voltage4–32 V DC

Turn-off voltage≤ 2 V DC

Control current≤ 10 mA

Load voltage30–480 V AC

OutputAnti-parallel SCR

SwitchingZero-cross (Z)

On-state voltage drop< 1.5 V

Off-state leakage current≤ 3 mA

RC snubber / input indicatorBuilt-in / LED

Dielectric strength> 3000 V AC

Operating temperature−20°C to +70°C

Use a suitable heat sink and apply thermal grease evenly between the metal base and heat sink. Select appropriate over-voltage protection for inductive loads.

MGR-HZF / CONNECTION

Separate the command.
Switch the AC load.

The series PDF specifies 4–32 V DC control and 30–480 V AC load voltage. The load and relay output form a series circuit. Observe + and − at the control connector. The drawing follows the supplied front view: the large left and right studs are the AC load terminals; the two small centre terminals are vertically arranged, with + above and − below. The centre circle is the indicator.

For an inductive load, follow the PDF guidance for a varistor across the output terminals and confirm its rating for the actual circuit.

MGR-HZF / PRINCIPLE

Wait for zero.
Switch the load.

The Z version uses zero-cross triggering with anti-parallel SCRs. After a DC ON command, conduction begins near an AC voltage zero. After an OFF command, an SCR ceases conduction when load current falls to zero. This is on/off switching, not phase-angle regulation.

MGR-HZF / APPLICATION

Industrial heater control.

A temperature controller commands the industrial SSR in a process-heating cabinet. The PDF requires a heat sink at 10 A and air- or water-cooled heat dissipation at 40 A and above. Confirm the actual thermal design for the selected model.
