Storage
Pay attention to the following points during temporary & long-term storage.
1. Store the power supply in our packing box
2. Long-term storage would lead to electrolytic capacitor degradation, it should be powered up yearly, at least 5 hours power-on time, input voltage should be increased to rated value by voltage regulator.
Warranty
1. The warranty period of this product is 12 months, free repair within warranty period except for man‐made damages or irresistible forces.
The following cases during under warranty are not included in free-warranty scope:
(1). Incorrect operation & maintenance of the power source that cause fault.
(2). Natural loss of consumable material (shell, connector etc.)
(3). Manual damage caused by modification or dismantle
(4). Damage caused by external equipments or third-party product or plug-in units.
(5). Force majeure factors, such as fire, flood or input grid abnormal.
(6). Unilateral amendment or modification on our LOGO or part number.
(7). Fault caused by abnormal usage of power source.
(8). Other non-product quality causes
2. Reasonable maintenance & repair costs should be charged after warranty period.
