Transformer PZ-250 (220/380V - 42V): Reliable Replacement for TZE 1DF 250

Operator safety when working with lifting equipment is the number one priority. To prevent dangerous mains voltage from reaching the hoist's control pendant (push-button station), a step-down transformer is used in the circuit. The PZ-250 transformer (220.380V/42V) is a high-quality equivalent to the original Bulgarian TZE 1DF 250 (Balkansko Echo) transformer, making it perfectly suited for the repair and maintenance of electric hoists.

Purpose and Features of the PZ-250 Transformer

This transformer is designed to power AC control circuits with a voltage of 42 Volts. It converts the primary voltage (can be connected to either 220V or 380V) into a safe 42V, which is supplied to the contactors and the control pendant of the crane or hoist.

• Absolute Compatibility: The PZ-250 is a complete electrotechnical and dimensional equivalent of the Bulgarian TZE 1DF 250 transformer. It effortlessly fits into the standard mounting slots in the control cabinet of «Balkansko Echo» or «Skladova Tehnika» hoists.
• Versatile Connection: The primary winding has taps for connecting both single-phase (220V) and phase-to-phase (380V) supply voltage.
• Reliability and Durability: The reinforced winding insulation (impregnation class) protects the device from overheating, inter-turn short circuits, and vibrations typical for the operation of lifting mechanisms.

When is a Replacement Needed?

Replacing the control circuit transformer is usually required when:

1. There is an inter-turn short circuit or a break in the primary/secondary winding (the hoist stops responding to the pendant buttons).
2. The old transformer severely overheats and its insulation melts due to a short circuit in the control circuit (e.g., a damaged pendant cable).
3. Carrying out a scheduled major overhaul of the crane's electrical equipment.
