Transformer PZ-125 (PZ-125) 220/380V - 42V (Old-style): Reliable Power for Control Circuits

Ensuring operator safety and stable automation performance is the main priority when designing and repairing lifting equipment. The starting and protective step-down transformer PZ-125 (Old-style) is designed to reduce the mains voltage to a safe 42 Volts, which is used to power low-current control circuits.

In the «DETZ» online store, you can buy PZ-125 transformers, which have proven to be a reliable replacement for failed original units in Bulgarian electric hoists and industrial machine tools.

Key Features and Advantages of PZ-125 (Version 2)

The PZ-125 transformer with a capacity of 125 VA is an optimal solution for equipping control cabinets of medium-capacity jib cranes and hoists. Its main advantages are:

• Versatile Connection (220V / 380V): The primary winding has special taps that allow the device to be powered either from a single phase and neutral (220V) or from two phases (380V), making it absolutely universal for any type of electrical panel.
• Safe Output Voltage: A stable 42V AC voltage is generated on the secondary winding, completely eliminating the risk of electric shock when operating the hoist's push-button pendant.
• Version 2 Design: This modification features an optimized layout of terminal blocks and mounting holes, which significantly simplifies and speeds up the installation process in confined electrical panel spaces.
• Load Resistance: Deep vacuum impregnation of the windings with electrical insulating varnish protects the transformer from moisture, metal dust, and vibrations, preventing inter-turn short circuits.

Where is the PZ-125 Step-Down Transformer Used?

This model is one of the most in-demand items for industrial electrical repairs. The transformer is installed in:

• Electric hoists of Bulgarian and domestic production;
• Control cabinets of bridge, gantry, and jib cranes;
• Lathes, milling, and drilling machines (powering local lighting and contactor circuits);
• Conveyor systems and automated production lines.
