Casing Material Black flame-retardant and heat-resistant plastic(UL94 V-0) Isolation Voltage Test 1 minute, leakage current <0.5mA Isolation Capacitor Typical Product List Part No. Note: 1.“*” is model under developing; 2. To ensure the module work efficiently and reliably, during the operation, the min. output load should be no less than 10% of the rated load. If the actual power is too low, please connect a resister to the output terminal in parallel, with a recommenced resistance which is 10% of the rated power.

Design and Application Circuit Reference 1. Output load request a. To ensure the module work efficiently and reliably, the min. output load should be no less than 10% of the nominal load during operation; If the actual output power is indeed low, please connect a resister to the output terminal in parallel, with a recommended resistance which is 10% of the rated power. b. The maximum capacitive load is tested under nominal input full load, and cannot exceed the maximum capacitive load of output when using, otherwise it will make it difficult to startup and damage the product. 2. Recommended Circuit...
