WRB2405S-3WR2

WRB2405S-3WR2 is the SIP-8 ordering code for the YLPTEC WRB2405S-3WR2 isolated DC-DC module, listed word-for-word in the product selection table of YLPTEC’s own WRA(B)_S-3WR2 series specification. YLPTEC publishes no lifecycle grading system; the code is current in that specification. It converts a nominal 24 V input over a 2:1 range (18 V to 36 V) into a single 5 V output at up to 600 mA, for 3 W total, in a 22.0 mm by 9.5 mm by 12.0 mm SIP case, works over -40 °C to +85 °C, tolerates a sustained output short circuit with self-recovery and provides a remote on/off control. Two figures are deliberately not stated for this code: the series header prints two isolation ratings side by side without a readable per-model mapping, and the per-model efficiency and ripple figures sit in specification tables that could not be read reliably, so neither is claimed here rather than borrowed from another maker’s same-name module. The selection point is a 3 W isolated 24 V to 5 V conversion for industrial controls, instrumentation and isolated interface supplies. Selection advice: confirm the isolation rating in writing against the current YLPTEC specification revision before designing this module into a safety-relevant barrier. Parameters verified against the YLPTEC WRA(B)_S-3WR2 series specification (selection table and product characteristics).
