Description

  • NCP-3200 is a 3.2KW dual-purpose(Switching Power Supply and charger) rack-mounted AC/DC power supply with a 1U low profile design and high power density of up to 37W/inch. This series operates at 90~264VAC input voltage and offers the models with the DC output mostly demanded by the industry.
  • Each model is cooled by the built-in DC fan with fan speed control and working for the temperature up to 70°C. NCP-3200 provides vast design flexibility by equipping with PMBus and CANbus, two international communication protocols that can be selected for industrial control and power supply control, and can also be used directly with intelligent controller CMU2. Active current sharing up to 10 rack shelves (DHP-1UT-B) and the maximum power supply that can be connected in parallel is 40 units, remote ON/OFF control, auxiliary power, alarm signal, and others.

Voltage Drop Compensation

  • Remote Sense (For 24V/48V models under power supply mode only)
  • The Remote Sense compensates for voltage drop on the load wiring up to 0.5V

Local Sense (For 24V/48V models under power supply mode only)

  • The +S and and-S have to be connected to the +V(signal), and -V(signal), respectively, as the following diagram, in order to get the correct output voltage if Remote Sense is not used.

Output Voltage Programming (or, PV / remote voltage programming / remote adjust / margin programming / dynamic voltage trim)

  • In addition to the adjustment via the built-in potentiometer, the output voltage can be trimmed to 50~125% (24/48V models) or 50~120% (380V model) of the nominal voltage by applying EXTERNAL VOLTAGE.

Constant Current Level Programming (or, PC / remote current programming / dynamic current trim)

  • The constant current level can be trimmed to 20~100% of the rated current by applying EXTERNAL VOLTAGE.
  • If setting the output current to a much lower level, as output status turns to the constant current mode, it might cause a higher current ripple under such conditions.

  • The 100% output current is 133/67/9.6A.
  • Notice the output power does not overrate power (max.)

Remote ON-OFF Control

  • The power supply can be turned ON/OFF individually or along with other units by using the “Remote ON-OFF” function.

Parallel Operation

  • For parallel operation, please refer to the function manual of the DHP-1UT-B(HV) rack system.
  • Read the installation manual before using this device. For the NCP-3200-380 high output voltage model, the correct rack system DHP-1UT-BHV should be used.
  • Failure to do so will cause permanent damage.

Pin No. Function Description
1,2 -V Negative output terminal.
3,4 +V Positive output terminal.
5 +12V-AUX Auxiliary voltage output, 10.8~13.2V, referenced to GND-AUX (pin 7).

The maximum load current is 0.8A. This output has the built-in “Oring diodes” and is not controlled by the Remote ON/OFF control.
6 +5V-AUX Auxiliary voltage output,4.5~5.5V, reference to GND_AUX(pin7). The maximum load current is 0.3A.  The output has the built-in “Oring diodes” and is not controlled by the Remote ON/OFF control.
7 GND-AUX Auxiliary voltage output GND. The signal return is isolated from the output terminals (+V & -V).
