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.

Charging Curve (Charger mode only available for 24V/48V models)

By default, the unit operates in power supply mode, and it can be configured to charger mode by PMBus, CANBus or SBP-001.
By factory default, this charger performs the default curve which can be programmed via PMBus and CANBus.
To accommodate the parameters of the charging curve, SBP-001, the smart battery charging programmer designed by MEAN WELL, and a personal computer are needed. Please contact MEAN WELL for details.

Front Panel LED Indicators

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.

Switch Short	ON
Switch Open	OFF

PMBus Communication Interface
NCP-3200 supports PMBus Rev. 1.1 with a maximum 100KHz bus speed, allowing information reading, status monitoring, output trimming, etc. For details, please refer to the Function Manual.
CANBus Communication Interface
NCP-3200 supports CAN 2.0B with a maximum 250KHz bus speed, allowing information reading, status monitoring, output trimming, etc. For details, please refer to the User’s Manual.
Alarm Signal Output

There are 3 alarm signals, DC-OK, AC-OK and T-ALARM, in TTL signal form, on CN1. These signals are isolated from the output. The maximum sink current is 10mA.

DC-OK signal	Power Supply Mode Status	Charger Mode Status
“High” > 3.5~5.5V	Vout ≦ 77%±5%	Vout ≦ 66%±5%
“Low” < -0.5~0.5V	Vout ≧ 80%±5%	Vout ≧ 67%±5%
AC-OK signal	Power Supply and Charger Mode Status
---	---
“High” > 3.5~5.5V	Input voltage ≧ 87Vrms
“Low” < -0.5~0.5V	Input voltage ≦ 75Vrms
T-ALARM signal	Power Supply and Charger Mode Status
---	---
“High” > 3.5~5.5V	OFF(OTP or Fan Fail)
“Low” < -0.5~0.5V	ON(Normal Work)

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.
