JZ-22010C型高频自冷电源模块使用说明书(10)

到正确输出电压值。

The value of output voltage is not correct: modulate the voltage adjustment

on the front panel to get the correct value.

2. 模块上电后便过压保护：手动调节输出电压超过过压保护值或模块控制口输出电压调节端输入电压过高。

Module starts voltage-over limit protection after being powered: manually

modulate output voltage till the value is more than that of voltage-over limit protection. This trouble may also rise when the output voltage-modulation end of the module control port inputs over limit voltage.

3. 输出电压不稳：检查输入电压是否波动超过允许范围或负载严重突变。 Output voltage is not stable: check the input voltage to see if it fluctuate

beyond the sustain range, or if the load fluctuate continuously and greatly

4. 模块无输出电流：检查模块输入是否正常，直流输出线是否断路。

No output current: check the module to see if the input is normal or the DC

output wire is cut off.

5. 模块不均流：检查模块均流线插接是否可靠。

Module current is not equalizing: check if the connection of module equalizing current is right.

九、售后服务 After-Sales Service

JZ-22010C型高频自冷开关电源模块自售出之日保修一年。保修期内，模块出现非人为性故障，免费维修。保修期过后，模块出现故障，只收元件成本费。

JZ-22010C high-frequency self-cooling switch power-supply module is

guaranteed to keep in good repair for 1 year since the day when it is sold. During the year, it can be repaired free if the failure isn’t caused by person’s wrong action; and after the year, only the elements’ cost is charged.
