Transformer PZ-300 (PZ-300) 220/380V - 42V ( Old Model): Increased Power for Control Circuits

For the stable and safe operation of powerful lifting equipment and complex industrial machines, reliable automation power is required. The step-down starting and protective transformer PZ-300 (version 2) converts high mains voltage into a safe 42 Volts, protecting the operator when working with a push-button pendant.

In the «DETZ» online store, you can buy PZ-300 transformers with a capacity of 300 VA. This is a reinforced model that perfectly handles powering extensive control circuits involving a large number of magnetic contactors and relays.

Key Features and Advantages of PZ-300 (Version 2)

A power reserve of 300 VA makes this transformer an indispensable component when repairing or assembling electrical panels for heavy cranes and high-capacity hoists. Its main advantages are:

• Increased Load Capacity: The 300 VA capacity allows powering several powerful contactor coils, as well as sound and light signaling systems simultaneously without voltage drops.
• Versatile Connection (220V / 380V): Multiple taps on the primary winding make it easy to integrate the device into any circuit (powered by a single phase and neutral or by two phases).
• Safe 42V Output: The secondary winding outputs exactly 42V AC — the standard voltage for Bulgarian hoist and Soviet crane control pendants.
• Version 2 Design: The optimized design of terminal blocks and mounting points makes installation in a distribution cabinet more convenient and faster.
• Overheating Protection: High-quality electrical steel of the magnetic core and vacuum impregnation of the windings with varnish guarantee a long service life even under conditions of intense vibrations and temperature fluctuations.

Applications of the PZ-300 Transformer

High power and reliability make the PZ-300 an ideal choice for:

• High-capacity electric hoists (from 5 tons and above);
• Multi-motor bridge, gantry, and tower cranes;
• Complex machine tool equipment (drilling, turning, milling groups);
• Industrial automation systems and conveyor transport.
