Current drawn from each supply rail
Hello!
Does anyone know what the on-state but no-signal current draw is for UCD400, UCD180 and BP4078 modules, at the typical operating voltages? (+/-60V for UCD400 / BP4078 and +/-40V for UCD180) I know the current consumption is different in the negative and positive rails, but can anyone tell me how much in each case? Thanks! |

The nearest figures I can provide are for a UcD 180 using a +/- 30V supply.
With no load connected, the +ve rail draws c. 65mA, and the -ve rail 40mA. With a 4R load fitted, and no input, these figures change to c. 50mA from both rails. When 'turned off' the figure drops to c.10mA for both rails. Sorry, but my test PSU only goes up to +/- 30V ! |
