它可以连接到高达793 VAC / 650 VDC的系统。电压耦合器配件扩展了这个范围。IRDH275采用的AMP Plus测量原理满足现代电力系统的要求,包括纯直流系统、带整流器的系统和带变频驱动器(vfd)的系统。在具有高泄漏电容的系统中，IRDH275自 动适应以确保准确的读数。IRDH275具有实时显示系统绝缘电阻的数字显示器。所有设置都可以通过设备的内置菜单进行更改。IRDH275利用外部供电电压供电，允许断电系统也被监控。
IRDH275B-435
BENDERIRDH275B-435 is a high-performance DC isolation amplifier widely used in various industrial automation, robot control systems, and power systems. This product has the characteristics of high precision, high sensitivity, and high reliability, which can effectively isolate and amplify DC electrical signals, improve the stability and safety of the system. This device meets or exceeds the requirements of NEC 250.21 (B) and CEC 10-106 (2) for grounded detectors in ungrounded AC systems, as well as the requirements of NEC 250.167 (A) for ungrounded DC systems, which will be released in 2014. IRDH275 monitors grounding faults in ungrounded single-phase AC, three-phase AC, and DC systems by monitoring the insulation resistance of the system.

It can be connected to systems up to 793 VAC/650 VDC. The voltage coupler accessories have expanded this range. The AMP Plus measurement principle adopted by IRDH275 meets the requirements of modern power systems, including pure DC systems, systems with rectifiers, and systems with variable frequency drives (vfds). In systems with high leakage capacitance, IRDH275 automatically adapts to ensure accurate readings. IRDH275 has a digital display that displays the insulation resistance of the system in real-time. All settings can be changed through the device’s built-in menu. IRDH275 utilizes external power supply voltage to allow the power outage system to also be monitored.
