Product introduction
The SX series operation box/console is an adjustable AC voltage control unit designed to support power testing equipment such as test transformers and converters. It provides a smoothly adjustable 0–250 V AC output and integrates monitoring and protection functions to support safe and reliable testing.

Key features

• Monitoring: output current, instrument voltage, zero position, contactor status (open/close) and timer status.
• Protection: overcurrent protection implemented with an integrated timer relay.
• Enhanced timing: next-generation timer relay with an extended timing range (1 s to 99 h).
• Improved safety: high-precision current relay to enhance protection for personnel and equipment.
• Compact design: small footprint and lightweight construction for easy installation and transport.

Precautions

• Ensure the instrument is reliably grounded during use.
• Raise and lower voltage at a constant speed; avoid sudden acceleration or deceleration.
• Continuously monitor instruments during tests to detect unexpected conditions promptly.
• Handle the equipment carefully and keep it clean.
