Jinghua JSZD-1 DC Voltage Relay User Manual
The JSZD-1 series DC voltage relay is designed for DC systems and combines an integrated circuit core with factory‑developed modules and peripheral components. It functions both as an over/under‑voltage relay and a precise digital voltmeter, allowing direct display of measured and set values.
The manual explains how to configure over‑voltage and under‑voltage thresholds, describes wiring connections, and lists precautions such as correct polarity and contact behavior. Installation diagrams for the three mounting types (JSZD-1A, JSZD-1B, JSZD-10) are included. This manual is written in Chinese.

Questions answered in JSZD-1 manuals
How do I set the over‑voltage threshold?
Press the [Select] key to light the over‑voltage setting indicator, then adjust the potentiometer until the desired value appears on the display; the setting is then complete.
What are the contact types for over‑voltage and under‑voltage?
The over‑voltage contact is normally open and closes when over‑voltage occurs; the under‑voltage contact is normally closed and opens under normal voltage, closing only on under‑voltage or power loss.
