Electrical control with manual/auto switching; aging time supports fixed modes 1.5H/2H/4H/6H/12H, and manual setting, e.g. 2 hours 10 minutes |
| H |
Safety protection: |
Equipment grounding protection, leakage switch protection, smoke-alarm automatic power-off protection; door can only be opened when temperature threshold is reached, and other safety protections |
| I |
Control cabinet configuration: |
Optional: none |
| 4 |
Main system functions: |
| A |
Aging for precision devices such as BMS controllers, radar controllers, cameras, etc. |
| B |
Dedicated monitoring software can be professionally developed and configured, with independent intellectual property and no legal risk |
| D |
Dedicated aging monitoring software enjoys lifetime upgrade service; strong scalability saves repeated equipment investment |
| E |
Programmable functions: aging parameters, time setting, ON/OFF sequence editing (power-on/off tests of tested products), automatic voltage switching, load change, etc. |
| F |
Automatic timed power-off of tested products after aging completes, convenient for unattended operation |
| G |
Computer automatically displays pass/fail status of tested power supplies; multi-cart window view for centralized management, saving operators and improving production efficiency |
| H |
RS232-to-RS485 via opto-isolated converter, improving communication reliability and preventing lightning damage to equipment |
