Efficiency : 87% at 240 W output

(max. heat dissipation 36 W)

Regulation
Load 0 - 100% : 50 mV (10 mV when using sense points)
Line 198 - 265 V AC : 10 mV
Ripple + noise (BW = 20 MHz) : 5 mVrms, 15 mV p-p
Temp. coefficient : 5.10–5 per °C
Stability during 8 hrs : 3.10–4 (after 1 hr warm up)
Output impedance : 0.1 Ohm up to 100 kHz
Recovery time : 200 µs after 50 - 100% load step
Insulation
Input / output : 3750 Vrms (1 min.)
Input / case : 2500 Vrms (1 min.)
Output / case : 500 V DC
Hold-up time : 20 ms (24 V / 10 A, 230 V AC input)
Ambient temperature
Operating : –10 to +50 °C. Above 50 °C derate current linearly to 20% at 80 °C.
Storage : –40 to +85 °C.
Series operation : Up to 500 V total voltage
Parallel operation : At 90% of max. current (Internal current limit switch at low). The extra positive output

terminal, via a built-in Schottky diode, separates the output circuits when units are
operated in parallel.

Alarm circuit : A relay contact changes over when the output drops 10% below the set value.

Gold contact, rating max. 100 mA / 30 V.

Current limit : Constant power limit from 30 to 22 V, constant current below 22 V.

Current limit protects against continuous overload and short circuit.

OVL : Limits the maximum output voltage at about 33 V.
MTBF : 1 000 000 hrs
Dimensions and weight : Height 240 mm

Width 71 mm
Depth 156 mm
Weight 2.0 kg

Mounting :The 240S24 should be mounted vertically for optimal cooling. When mounted horizontally, put

internal current limit switch at low and keep the ambient temp. below 40 °C.

Remote sensing :The sense points (pin 8 and 10) are internally connected to + and – output (pin 6 and pin 12), but these links can be

removed when remote sensing is required. The voltage drop across the leads plus the load can never exceed the
supply maximum output rating. For example at 24 V 8 A it is possible to compensate 6 V (3 V per lead) because the
unit can supply max. 30 V 8 A.

Remote progr. :2 - 5 V between pin 14 and 10 gives 12 - 30 V output (internal switch in position P). Programming input is not

isolated (connected to – output).
Voltage adj. with :Is possible if an internal link and a resistor are removed.
