The BLS-1WR3 and A-S-1WR3 series are small-sized, high-efficiency, low-power, fixed-voltage input, isolated non-regulated single/dual output, DC/DC module power supplies provided by Hailingke for customers. This series of products is specifically designed for applications in on-board power systems where a set of voltages isolated from the input power supply needs to be generated. This product is applicable to: The input power supply voltage is relatively stable (voltage variation range ± 10%Vin) Isolation is required between input and output (isolation voltage ≤1500VDC). · There is no high requirement for the stability of the output voltage; Typical applications: pure digital circuit scenarios, general low-frequency analog circuit scenarios, relay drive circuits, data exchange circuit scenarios, etc.
Product Features:
Constant voltage input, isolated non-regulated output, power 1W, isolated voltage :1500VDC, low no-load power consumption :0.025W(TyP.), efficiency: up to 90%, operating environment temperature :-40 °C to +85°C, mean time between failures (MTBF) > 3.5 million hours (3500,000 HRS), output short-circuit protection: Continuous short-circuit protection Automatic recovery of small SIP package, plastic housing, international standard pin mode ripple/noise (20MHz bandwidth):30 MVP-P (Typ.)
