This document provides the operating instructions of Kohshin Electric servo motors, including features, specifications, installation instructions, operating instructions, maintenance and maintenance
This manual provides detailed instructions for the use, installation, and maintenance of Kohshin Electric current sensors, covering the HC, HD, HS, HM, and HA‑BR series. It includes safety warnings, recommended wiring practices, and guidelines for handling and soldering the devices.
The document also lists the electrical characteristics, performance limits, and environmental specifications for each sensor type, along with export and usage limitations for special applications.
| Rated primary current | 50 A ~ 100 A |
|---|---|
| Rated output voltage | DC +5 V at 50/60 Hz |
| Response time | ≤ 500 ms (to 90 % point) |
| Load resistance | 5 kΩ |
| Control power supply | +15 V ± 5 % |
| Operating temperature range | -10 °C ~ +55 °C |
| Insulation resistance | ≥ 10 MΩ (500 V DC) |
| Dielectric withstand voltage | 2500 V AC for 1 min |
A capacitor of approximately 0.1 µF should be connected between the control power supply and GND.
Flow solder: about 250 °C for 5 seconds; Hand solder: about 280‑300 °C for 3 seconds (Pb‑free flow solder: 260 °C for 5 seconds; Pb‑free hand solder: 340 °C for 4 seconds).
Erroneous connection of the control terminals can instantly destroy the internal circuits.
PCB‑mounting type sensors should be attached firmly so they are not separated from the installation board by more than 0.5 mm.
