MATSUSADA DRJ programmable AC/DC power supply

Producer: MATSUSADA PRECISION

Category: Standard AC/DC programmable power supply Tags: AC battery, PROGRAMMABLE AC POWER SOURCE

MATSUSADA DRJ Series is a compact, lightweight power supply with both AC and DC output, programmable that can output stable and accurate sine waves. This AC power source supports both space saving and high quality AC power output, which is essential in experiments, evaluation tests, production lines, etc. In addition to compactness, the MATSUSADA DRJ series also uses universal AC input and a universal outlet on the front panel, allowing use by users worldwide. A model with an intermittent test feature (optional) has now been added to the product line, allowing equipment to be evaluated or tested with AC input under power interruption and input instability conditions. MATSUSADA DRJ features:

Universal socket on front panel
Check for instantaneous power failure for AC input devices (optional)
Three-phase AC output, three-wire single-phase AC output (optional) in 2 units

Note
DRJ series is not available to such applications where electric power is infused externally or renewable to behavior is made. Therefore they are not suitable for such devices that “returning generated electric power to AC line” or “being connected directly to the commercial system”.
In using the devices above, user our high-speed four-quadrant bipolar power sources with sink current function.

Functions MATSUSADA DRJ

Compact

Since it is a bipolar power supply with switching amplifier method, its volume is extremely compact in approximately 1/6 compared with linear amplifier method. In addition, its compact design with only 5.5 inches (140 mm) width and approximately 5 kg weight allows it to be installed anywhere. The handle makes it easy to carry.

Wide Range of Output Voltage and Frequency

DRJ series can be used for various AC input devices. It is also capable of DC output and thus it can be used in various applications.

AC output: Voltage: 0 to 150 V/300 V, Frequency: 1 Hz to 550 Hz

DC output: Voltage: 0 to +212 V/-212 V/0 to +424 V/-424 V

Momentary Power Interruption Mode (-LPfl Option)

It is possible to conduct momentary power interruption testing of the AC Input devices simply.
It can reproduce the situations where AC Input line is unstable or momentary power interruption happens, thus the operating conditions of AC Input device (tested device) can be checked under such environment.

When the momentary power failure operation is needed in three-phase output, the model which is equipped with -LPfl option is necessary as the model to be in charge of phase U. Please refer to “Options”.

Setting time of momentary power interruption

AC Output ON/OFF in Accordance with The Input AC Supply ON/OFF (-LN Option)

This allows users to output state auto-recovery prevention (former: power failure protection) after input AC supply's recovery from stoppage, without pressing OUTPUT button on the front panel. Thus remote re-activation without touching/accessing power supply at all can be realized.

High Peak Current

DRJ series addresses 20 A peak current (in Lo range).
It can output up to four crest factors and is ideal for capacitor input load.

Universal Type Outlet

Power supply has the universal output outlet on the front panel so that various types of worldwide plugs can be used without adapter. This helps user's grobal product development and testing work ever convenient and borderless.

Safety Functions

The DRJ series is equipped with a safety function to protect the power supply and connected load. For example, if an abnormal current flows, such as a short circuit, the output is immediately stopped. However, if a load with an inrush current is connected, the output may be stopped by the overcurrent protection function. In this case, use a product with a margin for current output or use the DRK series with a current limit function. Some loads have inrush currents that flow more than 10 times the rated current.

Various Output Modes

Three-phase output
Single phase three-wire output
Master/Slave

It is capable of three-phase output, single phase three-wire output and master/slave connection as options.

Three-phase output (OPTION)

It allows three-phase AC testing and evaluation even on locations where only a single phase 100 V/200 V is available. Its space-saving design with 5.51 inches/140 mm x 3 = 16.54 inches/420 mm width even when three-phase output is configured allows it to be used anywhere.

Three-phase AC system in a rack — A special rack mount adapter is available.

L1p3wm, -L1p3ws *¹ *²: Single phase three-wire connection
Single phase three-wire output mode is available. Each unit can also be used as a single-phase output AC power source.

It is possible to choose only one from (-L1p3wm, -L1p3ws), (-LPhu, -LPhv,-LPhw) or (-LMsm, -LMss). It is necessary to equip each power supply with every option.
To use an interface option (-LUs1, -LGb or -LGob), add only to the master unit (-L1p3wm, -LPhu or -LMsm). It is not required for the slave unit.
If the momentary power failure operation is needed in three-phase output, -LPhu optional model which is also equipped with -LPfl option is necessary. -LPhv or -LPhw optional models need not necessarily be equipped with -LPfl option. However, when the momentary power failure operation is needed in single-phase output, that is, when one DRJ is used alone, -LPfl option is necessary. Therefore, when DRJ can be used alone and asked for the momentary power failure operation, it is necessary to each equip DRJ with -LPfl option.
For high-accuracy tests and measurements, other models of Matsusada high-speed response bipolar power supplies and amplifiers are available.
These options cannot be selected together.

It is also possible to install this product in a 19-inch rack by using the special rack mount adapter (model: RMO-133H-DRJ ). For details, please contact our sales representatives.
