Product Specifications

Product Description

Features:

1.international AC input range
2.high efficiency,low working temperature
3.soft- start circuit,limiting AC surge current soft-start
4.short circuit, overload, over voltage protected
5.compact size, light weight
6.100% full load burn-in test
7.Built-in EMI filter, low ripple noise
8.low cost, high reliability
9.CE and ROHS approvals

Note:

1. all parameters are specified at 230vac input, rated load, 25°c 70% rh ambient
2. tolerance: include set up tolerance, line regulation, load regulation
3. ripple & noise are measured at 20mhz by using a 12" twisted pair terminated with a 0.1uf & 47uf capacitor
4. line regulation is measured from low line to high line at rated load
5. load regulation is measured from 0% to 100% rated load

Application:

It is suitable for all kinds of led product with DC12V or DC24V
