Transformateur de puissance monophasé à isolation contrôlée Bk100va-5kva

Key features & benefits

• Capacity range: 100 VA – 5 kVA (wide range to fit small control panels up to medium machinery).
• Flexible input options: Custom input voltages available — typical choices: 360 V / 380 V / 415 V / 440 V (single-phase or as required).
• Customizable outputs: Standard outputs include 12 V, 24 V, 36 V, 48 V, 60 V, 120 V, 220 V (other voltages available on request).
• Thyristor (SCR) control module: Smooth, fast regulation with closed-loop feedback to keep the output steady under varying load or supply.
• High efficiency: Typical efficiency up to 98% depending on model and load.
• Strong insulation & safety: Insulation resistance ≥ 50 MΩ; dielectric withstand test 3000 V for 1 minute (no breakdown).
• Durable construction: Silicon-steel laminations in the core for low loss and long service life.
• Easy wiring options: Jumper/linkable terminals for multi-tap or different voltage configurations (makes installation flexible).

Signification du modèle

Paramètres techniques

How it works (simple)

Input feeds the transformer core.
The SCR control module adjusts conduction angle to regulate output voltage.
A feedback circuit constantly monitors output vs. setpoint and corrects the SCR firing to keep voltage stable.
This closed-loop approach gives smooth regulation and protects sensitive control devices from surges or sags.

FAQ

Q1: What makes a BK transformer different from a regular single-phase transformer?
A: The BK is a control/isolation transformer that includes a thyristor (SCR) module and feedback for closed-loop voltage regulation. A standard single-phase transformer only steps voltage up or down and does not actively regulate output under changing input conditions.

Q2: How do I choose the right size (VA/kVA)?
A: Add up the control circuit load in VA, then add 20–25% margin for start-up or surge current. If unsure, send your load list to our engineers and we’ll recommend the right BK transformer size.

Q3: Can you customize voltages and enclosures for export?
A: Yes. We provide custom input/output voltages, 50/60 Hz options, and export-grade enclosures. ZHENGXI supports CE and RoHS requirements.
