1. Earthquake-resistant housing fixing bolt installation available (optional)
Optional fixing bolts are available that can be attached to the top of the housing (eyebolt type: cannot be hung). This can be used as a simple earthquake-proof measure.
2. A convenient power supply lamp for checking power supply
Equipped as standard with a lamp that lets you know at a glance whether power is being received from the grid
3. Emergency stop button and interlock function are standard features
Two safety features instantly stop output in an emergency to protect users from high voltage
4. Front intake, rear exhaust design
This increases the degree of freedom in the layout of the enclosure.
5. Equipped with screw holes for fixing patrol lights
When the AO-19 option is installed, the rear panel DI/DO can be easily connected to the PATLITE SL08 series.
6. Easy operation with direct keys
Function call keys allow for intuitive operation.
7. Earthquake-resistant anchor bolt fixing bracket installation available (optional)
The four corners of the housing are firmly fixed to prevent shaking.
8.Leveler included as standard
Can be used for simple housing fixing.
ⒶFrequency , voltage, current, and power factor (or power) can be measured simultaneously like a power meter.
Ⓑ In addition to the Up/Down buttons for the setting value, a button for changing the digits has been added, making the setting easier than with previous models.
Ⓒ In addition to the conventional function for measuring each phase and line voltage, a new LINE/PHASE switching function has been added, allowing you to set the voltage for each phase voltage and line voltage. Direct voltage setting is now possible.
Ⓓ An illuminated output switch is used so that the input status can be seen at a glance.
Ⓔ By connecting a USB memory to the dedicated USB port, you can save and load program settings to the USB memory. Firmware can also be updated using this port.
A soft start time setting is provided when the output is turned on, allowing the voltage to increase without starting current during motor starting operation.
In program mode, the ramp-up time can be adjusted for each step, allowing the voltage to increase without starting current during motor starting operation.
LAN/USB/RS-232C are provided as standard. A GB-IB/RS-232C converter is also available as an option.
External Control
In addition to PC-based communication control, it also supports external analog control (optional) of 0 to 10Vdc. The voltage and frequency can be controlled from a PLC (Programmable Logic Controller) using the standard equipped PLC input and DI/DO.

This compensates for voltage drops when large currents flow, allowing for more accurate voltage settings at the sense point. This is effective when the AC power supply and the load are far apart.
Motors, compressors, and other devices have a large temporary starting current. If this starting current activates the protection circuit of the AC power supply, testing will be impossible. The time-limited current limit function was developed to prevent this, so you can use it safely to test motors, compressors, and other devices.
By repeating steps 1 to 3, it is possible to drive the motor.
It is possible to supply instantaneous overloads of three times the rated capacity for one second or less (voltage droop drops to 110% for times longer than one second).When testing motors or compressors with large inrush currents or starting currents, it is possible to start (rotate) them without voltage droop.

The input voltage and wiring can be changed. It is compatible with the grid input voltage of any country. Please specify when ordering.
*If no specification is given, the standard is three-phase, three-wire 200V.
Available setting values
It can supply three to four times the inrush current of conventional models, and can withstand repeated crest factors up to four times the specified level.
When an input current (reverse current) is detected from the output terminal of the AC power supply, an alarm is displayed and the output is quickly turned off to protect the AC power supply itself. This protects the main unit from reverse currents such as reverse currents that occur when electric motors such as motors and compressors stop, and reverse currents such as instantaneous reverse currents that occur from a PCS when connected in parallel with a resistive load as a system simulation power supply, allowing you to use the unit with peace of mind.
The QA-S2-V6 series supports output voltages up to 600V, making it possible to perform voltage doubling tests in accordance with each manufacturer's internal regulations.In addition, since it can simulate the line voltage for one phase in a three-phase, three-wire 400V system, it is possible to reproduce the power supply voltage when using only one phase from a three-phase voltage source.
