Product Overview

The JBK Series Custom Manual Multi-Tap Control Transformer is specially designed for industrial machine tools and automation equipment. It accurately converts 120V input voltage into stable 24V control power while supporting manual tap adjustment and custom voltage configurations.

Widely used in North American standard machine tools, imported equipment retrofits, automation control cabinets, and industrial control systems, the transformer provides safe, stable, and reliable low-voltage power for industrial control circuits.

This 75VA model is ideal for small control loads such as relays, indicator lights, solenoid valves, and signal circuits.

Key Features
