1W isolated DC-DC with Fixed Input Voltage; unregulated Single Output

Description

B_S-1WR2&B-D-1WR2 series is designed for use in distributed power supply systems and especially suitable in applications such as pure digital circuits,low frequency analog circuits,relay-driven circuits and data switching circuits,where:

1. The voltage of the input power supply is relatively stable with a variation of ±10%Vin or less;

2. An input to output isolation voltage of up to 1500VDC is necessary;

3. The requirement for a tight output regulation and low ripple&noise is not as strict.

FEATURES

  • Continuous short-circuit protection
  • High efficiency up to 80%
  • Operating ambient temperature -40℃ to +105℃
  • Compact SIP/DIP package
  • Industry standard pin-out
  • I/O isolation test voltage 1.5k VDC
  • IEC60950, UL60950, EN60950 approval
