Hold-up time : 15 ms at full load, 30 ms at half load (220 V AC).
Se ries op er a tion : Up to 500 V to tal volt age. Up to 1 kV for 150SX75-75 and 200-200.

Cur rent limit : The cur rent limit is fixed and pro tects the power sup ply dur ing over load ing and short cir-
cuiting. Con tin u ous over load and short cir cuit does not harm the unit.
10% more cur rent can be taken at the low end of the volt age range.
Volt age limit : For safety a sec ond reg u la tion cir cuit lim its the out put volt age to about 10% above its
range in case the nor mal reg u la tion loop fails.
Volt age ad just ment : The out put volt age is con tin u ously vari able over the whole range with a 20 turn screw-
driver ad just ment through the front panel.
Re mote con trol : Volt age con trol with an ex ter nal po ten ti om e ter is pos si ble af ter some small in ter nal

Re mote pro gram ming : Re mote pro gram ming of the out put volt age is pos si ble af ter chang ing an in ter nal link on
the PCB. An an a log volt age of 5 V be tween PROG. and S– cor re sponds with the max out-
put volt age. Note: In dual mode S– is at a neg a tive po lar ity.
Re mote sens ing : The sense points are in ter nally con nected to + and – out put. These links have to be re-
moved when re mote sens ing is re quired. The max. sense range is 2 V per load lead for
SX15-15 and 0.5 V for SX5. How ever the volt age across the leads plus the load cannot

Led lamp : A green led lamp at the front panel in di cates the out put.
MTBF : 1 000 000 hrs
Dim. and weight : 75SX h x w x d = 100 x 35.5 x 172 mm, 0.6 kg

Be cause the sense points of the reg u la tion are in ter nally con -
nected to the + and –15 V ter mi nals, the to tal volt age V1 + V2 is
kept con stant.
When V1 and V2 are equally loaded the zero point will be in the
mid dle.
With un equal loads a slight zero shift will oc cur.
Asym met ri cal over load ing and shortcircuiting will not
dam age the unit.
