Measurement auto-transformer SX

electrical power supplycurrentinstrument

Product introduction:
The SX series test transformer operating box is a control console designed to supply a smooth, continuous 0–250V AC output for electrical testing. It supports test transformers, current risers and related equipment and integrates digital display, monitoring and protection functions for controlled test procedures.

Technical parameters:

• Input voltage: 220V ±10%, 50Hz
• Output voltage: 0–250V AC
• Output capacity: 5 kVA
• Instrument voltage: 100V / 100kV
• Timing range: 1 s – 99 h
• Operating ambient temperature: -20°C to 50°C

Product features:

• Monitoring: displays output current, instrument voltage, zero position, contactor status (open/closed) and timer status on the digital display.
• Protection: integrated overcurrent protection with timer relay to limit risk during tests.
• Timing: next‑generation timer relay with extended timing range (1 s – 99 h) for flexible test sequences.
• Safety components: high‑precision current relay for improved detection and personnel/equipment protection.
• Compact design: small footprint and lightweight construction to facilitate installation and transport.

Precautions:

• Ensure the unit is reliably grounded before use.
• Adjust voltage up and down at a steady rate; avoid sudden acceleration or deceleration.
• Continuously monitor instruments during tests to detect anomalies promptly.
• Handle the equipment with care and keep it clean to maintain reliable operation.
