voltage is required in a distributed power supply system.
Short circuit protection (SCP)
RoHS Compliance
No External Component
Required
These products apply to:
1) Where the voltage of the input power supply is stable
(voltage variation: 10ꢀ%in)ꢁ
PCB Mounting
2) Where isolation between input and output is necessary
(isolation voltage ≤1500%DC)ꢁ
3) Where the output voltage regulation and the ripple & noise of the output
voltage is not strictly required.
Typical application: digit circuit conditionꢁ normal low-frequency artificial
circuit conditionꢁ relay drive circuit and data switching circuit condition, etc.
