Hold-up time : 20 ms (24 V / 10 A, 230 V AC in put)
Am bi ent tem per a ture : Op er ating: –10 to +50 °C. Above 50 °C de rate cur rent lin early to 20% at 80 °C.

Se ries op er a tion : Up to 500 V to tal volt age
Par al lel op er a tion : At 90% of max. cur rent (In ter nal cur rent limit switch at low). The ex tra pos i tive out put

Alarm cir cuit : A re lay con tact changes over when the out put drops 10% be low the set value.

Cur rent limit : Con stant power limit from 30 to 22 V, con stant cur rent be low 22 V.

OVL : Limits the max i mum out put volt age at about 33 V.

Gold con tact, rat ing max. 100 mA / 30 V.

Cur rent limit pro tects against con tin u ous over load and short cir cuit.

CL15

Mount ing : The 240 S 24 should be mounted ver ti cally for op ti mal cool ing. When mounted hor i zon tally, put

in ter nal cur rent limit switch at low and keep the am bi ent temp. be low 40 °C.

Re mote sens ing : The sense points (pin 8 and 10) are in ter nally con nected to + and – out put (pin 6 and pin 12), but

these links can be re moved when re mote sens ing is re quired. The volt age drop across the leads
plus the load can never ex ceed the sup ply max i mum out put rat ing. For ex am ple at 24 V 8 A it is
pos si ble to com pen sate 6 V (3 V per lead) be cause the unit can sup ply max. 30 V 8 A.

Re mote progr. : 2 - 5 V be tween pin 14 and 10 gives 12 - 30 V out put (in ter nal switch in po si tion P). Pro gramming in -

put is not iso lated (con nected to – out put).
