LZS power replacement and troubleshooting

Although LZS-A1000-3 outperforms the old model in terms of electrical performance, the following differences need to be particularly noted in replacement projects:

Project LZS-1000-3 (old) LZS-A1000-3 (new) replacement action

The external dimensions are slightly different, 5.62 "× 4.75" × 10.5 ". Please check the installation hole position and it may require an adapter plate

Control interface may be different. Remake control cable for 15 pin D-sub+TB201

Remote power on/off logic may be opposite, low level or open circuit=turn off. Adjust external circuit according to actual logic

The current sharing pins may be different. When pin 5 is connected in parallel with the current sharing bus, it needs to be confirmed

Output terminal screw terminal busbar may require replacement of load wiring terminals

Suggestion: Before replacing, download the complete manual of LZS-A1000-3 from the official website and compare the wiring diagrams of the old system item by item. If possible, test a single new power supply offline to confirm that all remote control signals and alarm signals are working properly, and then replace them in bulk.
