Description
The REC20-xxxxS_DZ -series offer single and dual regulated outputs in a 2”x1” package with 1.6kVDC
isolation and are suitable for higher power industrial applications. Remote on/off control is standard.
The higher current outputs have raised output voltages to compensate for track losses as standard. The
converter is fully certified to UL/EN/IEC safety standards.

a = trim up factor
b = trim down factor
DVout = Vout - Vouttrimmed
a = q 2.5V r * 2.3kΩ = 1.843kΩ
(5.1V + 0.51V) - 2.5V Rup = q1.843kΩ * 2.2kΩ r - 9.1kΩ = 2.255kΩ

Trim Up:
Vout = 5.1V, DVout = 0.51V (10%), Vref= 2.5V
Trim down:
Vout = 5.1V, DVout = -0.51V (-10%), Vref= 2.5V
b = q [5.1V + (-0.51V)] - 2.5V r * 2.2kΩ = 1.839kΩ
2.5V Rdown = q 1.839kΩ * 2.3kΩ r - 9.1kΩ = 0.080kΩ
