NOTES:

21. V+ Input Range = 19V to 30V for 15V output.

22. V- Input Range = -16V to -30V for -15V output.

23. Max IOUT = ±100mA.

24. Regulation:

Max Line = [---V----O-----U-----T---∆-(--I-V-n---O-i--t--Ui--a---T-l--)--]---∆----V----I--N--- × 100 = 0.075% ⁄ V

Max Load = V-----O----∆-U----VT----O-(--I--Un----i-T-t--i--a----l--) × 100 = 0.075% VOUT

NOTES:

25. Differential current sensor provides 60mV signal ≈ 5mA of

unbalance (Trip) current.

26. All Resistors are 1/2 Watt, ±10%.

27. RC selected for 3dB point at 200Hz.

28. C2 = AC bypass.

29. Offset adj. included in RTRIP.

30. Input impedance from 2 to 3 = 800kΩ.

31. With no input signal Terminal 8 (output) at 36V.
