MGR-DT22120EG solid state voltage regulator — MGR-DT22120EG · 220 V platform · 120 A representative model

01 / MODEL RANGE

Three naming platforms.

The middle current number identifies the maximum rated load current. Choose the 220 V or 380 V voltage-regulation platform first; the -II suffix identifies an alternate enclosure form.

220 V AC REGULATION

MGR-DT22--EG

22 denotes the 220 V AC voltage-regulation platform. Example: MGR-DT22120EG.

380 V AC REGULATION

MGR-DT38--EG

38 denotes the 380 V AC voltage-regulation platform. Select the current code to suit the load.

ALTERNATE ENCLOSURE

MGR-DT--EG-II

-II denotes a different product appearance / enclosure form. Confirm dimensions before installation.

03 / PARAMETERS

Fully isolated.
Precisely controlled.

The MGR-DT is an all-isolated single-phase AC voltage regulator module. Its control and power sections are electrically isolated, with synchronized phase detection and thyristor phase-angle control regulating the AC output.

01 / ISOLATION

Full electrical isolation

The power section is isolated from the low-level control circuit, as described in the MGR-DT catalogue.

02 / CONTROL

Multiple signal versions

Catalogue-listed options include 0–5 VDC and 4–20 mA (EG), 0–10 VDC (F), and 1–5 VDC (H). Available signal depends on the exact ordered variant.

03 / REGULATION

Phase-angle AC regulation

A synchronous transformer and phase-detection circuit provide thyristor trigger timing to regulate the AC output according to the control signal.

Product typeAll-isolated, single-phase AC voltage regulator (SSVR)

Voltage platformsDT22: 220 VAC nominal · DT38: 380 VAC nominal

Allowable input rangeDT22 / 220 VAC version: 165–240 VAC · DT38 / 380 VAC version: 285–420 VAC

Control signalsVariant-dependent: 0–5 VDC / 4–20 mA (EG), 0–10 VDC (F), or 1–5 VDC (H)

Isolation voltageMore than 2000 VAC between the power section, control section and module base

How to connect

Follow the actual front-terminal arrangement: AC supply to the upper pair, single-phase AC load to the lower pair, and the control signal to the matching side terminal.

4–20 mA: signal + to 4–20 mA; signal − / return to COM.
0–5 VDC: signal + to 0–5 VDC; 0 V / return to COM.
Use only one control input. +5 V is for the manual potentiometer circuit only.
