2 Phase Variable Transformer
Product Overview
Our 2 Phase Variable Transformer (Model TDGC2-5KVA, customizable)
is an energy-saving manually adjustable AC voltage regulator,
developed and manufactured by Shanghai Lepus Electrical Equipment
Co., Ltd. This TDGC2 series contact-type variac is purpose-built
for industrial, laboratory, and field scenarios requiring precise
manual output voltage adjustment, fully compliant with JB/T
100-1-2001 standards. It delivers full-capacity operation, high
efficiency, zero additional waveform distortion, and strong
instantaneous overload capability for continuous long-term duty.
Widely used for voltage regulation, temperature control, motor
speed adjustment, dimming, and power control, it is the ideal power
solution for motor testing, voltage test benches, factory power
systems, CNC machines, photovoltaic systems, precision equipment,
generators, and EV charging stations worldwide.
Key Features & Advantages
- High Precision & Wide Regulation Range: 0-250VAC adjustable output
with ±2% accuracy, supporting 50/60Hz frequency and full
compatibility with resistive, inductive, and capacitive industrial
loads.
- Premium Core Components: Pure copper coil with microcomputer
control board, paired with high-conductivity double carbon brushes
for stable voltage regulation, low losses, and high working
efficiency.
- Zero Waveform Distortion: No additional output waveform distortion,
ensuring clean power supply for sensitive precision instruments and
test equipment without signal interference.
- Intuitive Operation & Real-Time Monitoring: Simple rotary knob for
manual voltage adjustment, with a digital display providing
real-time voltage data tracking and reliable high-insulation
terminals for safe operation.
- Durable Industrial Design: Sturdy metallic enclosure, 2500V
dielectric strength, stable operation in -15℃ to +45℃ environments,
with long service life and high reliability for harsh industrial
settings.
