Features, Applications

This LDD240-WU DC/DC converter is the optimal response to the applications where compactness and high reliability are requested. It is isolated and offers a wide range of input and output voltages. Simple but elegant look and ease of installation make it ideal for various industrial applications.

240 W output power (voltage dependent) Converts any voltage between 11 V and V to any voltage between 5 V and 55 V High efficiency and compact size Constant current or hiccup mode limitation, user settable Digital Power regulation Isolated topology (4.2 kVDC) Modbus over USB interface for control and monitoring Multiple protections integrated Parallelable for power or redundancy (integrated ORing circuitry)

Industrial machine control Process control Energy management Remote control systems

Technical parameters are typical, measured in laboratory environment at 25C and 24 VDC input and output voltage, at nominal values, after minimum 5 minutes of operation.

Overload and short circuit: Constant current or Hiccup mode (user settable) Thermal protection Output overvoltage 120% of Vout active self-tracking 7 segment, 2 digit display 3 programming keys OK - dry contact (NO, 24 VDC 1 A) Modbus over USB interface Possible for power or redundancy with integrated ORing circuitry - 92% (depending on Vin / Vout) 28 W (depending on Vin / Vout)

Ripple and Noise are measured with 20 MHz bandwidth, probe terminated with 0.1 F MKP parallel capacitor. Pay attention, set the operating mode to "parallel" when connecting more units in parallel, see Instruction Manual for details.

NOTE: Power rating, losses, efficiency, ripple, thermal behaviour and start-up may change outside of the nominal rated input range. Contact factory for details.
