Transformers

Series in this category

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.

Selection points

• Confirm whether galvanic isolation is required or an autotransformer is sufficient.
• Control transformers are sized by the control circuit load, not the main motor.
• Portable lighting transformers must match the site safety voltage (36V/24V/12V).
• State primary and secondary voltages, frequency and connection group.
• Enclosure and IP rating follow the installation environment.

Where it is used

• Machine tool control circuits
• Site and tunnel lighting
• Industrial isolation and voltage conversion
• Export equipment voltage matching
