1 Overview
The JY-7D series integrated circuit DC voltage relay is used in DC relay protection devices to monitor DC voltage and serve as an overvoltage protection or undervoltage lockout starting element.

2 Characteristics
2.1 Convenient setting, using a three position dial switch to set the voltage value, intuitive and convenient, without the need for calibration. Setting range: 60V~300V.
2.2 High precision, with an error of less than 2% and a small step difference of 1V.
2.3 High reliability, no shaking, no refusal to move, fast action, high return coefficient.
2.4 The measured voltage does not require an auxiliary power supply, and the wiring does not need to consider polarity.

Our company produces and sells various stainless steel products, and supports customized production of various non-standard products. Stainless steel products are mainly used in fields such as medicine and universities.
