Rack Mount Programmable Power Supplies

Programmable rack mount power supplies

ADM stocks the MEAN WELL range of programmable rack mount power supplies.

MEAN WELL was established in 1982 by Mr Jerry Lim, who still heads up the company today. In 1986 MEAN WELL started to produce a range of standard switch mode power supplies. The core philosophy of the company is to design and manufacture power supplies, which are highly reliable and very affordable.

MEAN WELL has three series of programmable rack mount power supplies:

Series

Typical Power Output*

RCP-1600

1600 Watts

RCP-2000

2000 Watts

DRP-3200

3200 Watts
*check data sheet for actual model selected

MEAN WELL rack mount power supplies are based on a modular design.

1U low profile racks are available that will accommodate either 3, or 5 power supply units. The power supply units themselves all have a current sharing feature, so that they can be connected in parallel.

All MEAN WELL’s rack mount power supplies are ‘hot swappable’, so you don’t need to power down to swap out a power supply that may have failed and all models have a remote ON/OFF function. This makes them highly desirable for use in data centres.

RCP-1600

Mean Well RCP-1600

There are three different models of the RCP-1600 available:

Model

Power Output

RCP-1600-12

12V / 125A

RCP-1600-24

24V / 67A

RCP-1600-48

48V / 33.5A

The rack is ordered as a separate item under part number RHP-1U.

Mean Well RHP-1U

Holding 5 power supplies, you have up to 8000 watts of power available, should you opt to use the current sharing function to connect all 5 power supply units in parallel.

There are 3 built-in alarm signals: DC OK, AC OK and Temperature alarm.

The output voltage and current can be programmed via applying an external voltage to the control inputs. This means the power supplies output can be varied throughout a process using a PLC, or other type of controller.

The range of adjustment available is shown in the below table:

Power Supply Unit

Manual VDC Adjust Range

Remote VDC Adjust Range

Remote Current Adjust Range

RCP-1600-12

11.5 ~ 15V

40~125% of the nominal voltage 20~100% of the rated current

RCP-1600-24

23.5 ~ 30V

RCP-1600-48

47.5 ~ 58.8V

There is also an auxiliary power output, which can deliver either 5V @ 0.3A, or 12V @ 0.8A.

RCP-2000

MEAN WELL RCP-2000

The RCP-2000 series power supplies share many of the features and functions found on the RCP-1600 mentioned above.

The RKP-1U mounting rack is ordered separately and can house up to 3 RCP-2000 power supplies.

Model

Power Output

RCP-2000-12

12V / 100A

RCP-2000-24

24V / 80A

RCP-2000-48

48V / 42A

Using the current sharing function, you enjoy a power output of up to 6000 Watts per rack.

The RCP-2000 boasts a wide range of useful functions, which makes it perfect for use in a wide range of applications:

  • Auxiliary power output: 5V @ 0.3A / 12V @ 0.8A
  • Remote adjustment of output voltage.
  • DC OK Signal
  • AC OK Signal
  • Over Temperature Warning
  • Fan Fail Signal

As with the RCP-1600 remote adjustment of the output voltage is achieved by applying an external voltage to the relevant control terminals on the power supply.

Power Supply Unit

Voltage Adjust Range (Manual)

Voltage Adjust Range (Remote)

RCP-2000-12

10.5 ~ 14V

90 ~ 110% of nominal output voltage

RCP-2000-24

21 ~ 28V

RCP-2000-48

42 ~ 56V

A remote-control unit is available for the RCP-2000 series power supplies under part number RKP-CMU1.

MEAN WELL RKP-CMU

This allows you to monitor the output voltage of the power supplies, the current draw and temperature level. Alarm signals can be set to warn of a power supply operating outside of expected parameters, giving an early indication that something could be wrong.

DRP-3200

MEAN WELL DRP-3200

The DRP-3200 series programmable rack mount power supplies have recently been added to the MEAN WELL range.

ADM plans to stock these in the future.

The DRP-3200 features a, I2C and supports the PMBus protocol. CANBus protocol support is available as an option. This means the DRP-3200 can easily be integrated into higher level control systems.

As with the RCP-1600, both the output current and output voltages are programmable.

Power Supply Unit

Manual VDC Adjust Range

Remote VDC Adjust Range

Remote Current Adjust Range

DRP-3200-24

23.5 ~ 30V

50~125% of the nominal voltage 20~100% of the rated current

DRP-3200-48

47.5 ~ 58.8V

Again, there are built-in alarm signals to indicate the status of the DC output and to flag if the temperature of the unit exceeds 60°C.

The rack is ordered as a separate item under part number DHP-1UT and holds up to 4 units.

The DRP-3200 features MEAN WELL’s current sharing function, which means one rack can deliver up to 12,800 Watts. In fact, a total of 8 units can be connected in parallel to deliver a total of 25,600 Watts!

All of MEAN WELL’s rack mount power supplies are backed by a 5 year warranty.
