Output Current Adjustment by Variable Resistor
+Vout
Control
By connecting a variable resistor between control
and GND, simple dimming can be achieved.
Capacitor is optional for HF noise rejection.
Recommended value is 0.22 µF.
LDU
-Vin
- Vout
The output current can be determined using the equation:
Where the value of R is between 0 and 2 MΩ, the
maximum adjustment range of output current is 25% to 90%
(For Vin-Vout, LDU08 & 24: <20 VDC, LDU48: <30 VDC )
For LDU08-24
Iout =
Iout nom x R
For LDU48
(R + 200 k)
Iout =
Iout nom x R
(R + 50 k)
