Portable Single Phase Relay Tester IEC 61010 Compliant Maximum Output Current 0-250a Accuracy 0.5%

Portable Single Phase Relay Tester IEC 61010 Compliant Maximum Output Current 0-250a Accuracy 0.5%

Product Applications

This product is primarily used for on-site calibration and performance testing of various relays, particularly for testing the operating characteristics of overcurrent and overvoltage relays in power engineering companies. It also meets the needs of relay manufacturers for factory inspection and equipment status assessment during power operations and maintenance, providing data support for relay reliability.

Product Highlights

• Portable and Durable: The compact aluminum alloy body (340×270×260mm) and 18kg weight allow for portable field testing. A wide storage temperature range of -40°C to 70°C accommodates harsh environments.
• High-Precision Output: Current is adjustable from 0-250A and voltage from 0-300V (DC) with an accuracy of 0.5%. AC True RMS and DC Average measurements ensure reliable data.
• Comprehensive Safety Protection: Built-in automatic short-circuit, overload, and over-range protection, along with a fully isolated output circuit, prevents damage to equipment and personnel during testing. Multifunctional integration: Supports AC/DC voltage/current output, electronic stopwatch (0.1ms resolution), and RS232 data transmission, allowing for complete testing without additional equipment.
