Vin, 24Vout and after warm-up unless otherwise stated) RBBA3000 Series The RBBA3000 series offers the feature of trimming the output voltage over a range between 0V and 60V by using precision trim resistors between the Trim and -Sense pin (1% recommended). Undriven Trim pin will set Vout to 0VDC. Additionally the Trim pin can be driven from an external voltage source: REMOTE SENSE +Vin -Vin-Vin +Vin Trim -Sense +Sense RW -Vout +Vout RTrim +Vout -Vout RW ... wire losses RTrim ... trim resistor The output voltage can be adjusted via the Trim and -Sense functions. The maximum output voltage from Trim and -Sense function combined is 60VDC. The maximum allowed voltage between +Sense and +Vout pins is 6VDC. Derating may be required when using trim and/or sense functions.
