Wide & Ultra Low Voltage Stabilizers & AVR, 500VA–3500KVA

Single-phase AC Voltage Stabilizer

Relay, servo-motor, SCR and precision-purified single-phase stabilizers for office, household, laboratory and medical equipment. Export versions can be configured for 110V/120V supply systems.

TM Relay-type Stabilizer

Relay tap switching with a colour LED display. A proven, low-maintenance single-phase solution for office and household equipment on unstable supply.

BTM Relay-type Stabilizer

Vertical cabinet construction with input-current and fault-record readout, for wall-mounted or stand-alone installation.

WTM Relay-type Stabilizer

Wide input window from AC 80V with multi-standard sockets, designed for export markets where supply quality varies widely.

SVC Servo-type Stabilizer

Servo-motor driven carbon brush regulation gives continuous, smooth correction with ±3% accuracy.

SVC-N Servo-type Stabilizer

Servo regulation with selectable 220V or 110V output, for equipment imported from 110V regions.

TND Servo-type Stabilizer

The widest single-phase servo range we build, from bench-top 1KVA units to 60KVA floor-standing cabinets, in conventional or low-voltage input versions.

JJW Precision Purified Stabilizer

SCR regulation with 1% accuracy and low added waveform distortion, for instruments and medical equipment that cannot tolerate step changes.

Three-phase Industrial Voltage Stabilizer

SCR static, servo type, split-phase and outdoor three-phase stabilizers for printing presses, CNC machining centres, laser cutters, injection moulding and complete production lines.

ZBW-S Static Stabilizer

Contactless static regulation with independent per-phase control and seamless bypass to mains, for sensitive digital loads and fast voltage swings.

TNS Servo-type Stabilizer

Three-phase servo regulation from 15KVA to 120KVA with a colour HMI, for machine tools and production equipment.

SBW Power Stabilizer

Cabinet-built servo stabilizer for heavy three-phase loads, from 50KVA to 800KVA, for whole-line and whole-plant protection.

SBW-F Split-phase Stabilizer

Square-cabinet construction with per-phase regulation, so unbalanced loads are corrected phase by phase, and cabinets combine for expansion.

SBW-H Outdoor Stabilizer

Weatherproof cabinet version for outdoor installation or plant-room locations without a controlled environment.

JSW Precision Purified Stabilizer

Three-phase four-wire SCR regulation with tunable accuracy from 1% to 5% and low added distortion, for sensitive process lines.

Transformers

Isolation, machine-tool control, portable lighting, three-phase control and three-phase dry-type isolation or autotransformers. Voltage levels are configurable at ordering.

ODK Isolation Transformer

Bench-top dry-type isolation transformer with 220V to 220V ratio, providing galvanic separation and noise decoupling for instruments.

BK Machine Tool Transformer

Control-circuit transformer for machine tools, stepping 440V/415V/380V/360V down to the control voltages a machine needs.

JBK Control Transformer

Compact control transformer family for 220V/380V control circuits, with output taps from 6V to 220V.

JMB Lighting Transformer

Portable site transformer delivering 36V/24V/12V safety lighting voltage from 220V or 380V supply.

SBK Three-phase Control Transformer

Three-phase control transformer with voltage accuracy ±1% and configurable primary and secondary voltages.

SG Isolation Transformer

Three-phase dry-type isolation transformer with Y/Δ connection, air cooled and cabinet built for plant installation.

OSG Autotransformer

Y-connected dry-type autotransformer for voltage conversion where galvanic isolation is not required, at higher efficiency and lower cost than an isolation unit.

Variac

Manual contact and motorized variable transformers with continuously adjustable output, used for test benches, ageing racks, motor speed testing and laboratory work. Built to JB/T10091.

TDGC2T Contact Variac

Bench-top variac with 0-300V continuously adjustable output, digital voltmeter and a rotary knob.

TDGC2 Single-phase Variac

Ring-core manual variac from 0.5KVA to 30KVA with 0-250V continuously adjustable output.

TSGC2 Three-phase Variac

Three-phase manual variac with 380V input and 0-430V continuously adjustable output, built to JB/T10091.

TDGC2J Motorized Regulator

Motorized single-phase variac for remote or repeated adjustment, with ring-core vertical construction.

TSGC2J Motorized Three-phase Regulator

Motorized three-phase variac from 10KVA to 120KVA with 0-430V adjustable output for test benches and production lines.
