Product Overview

Features

Constant Current (CC) automatic crossover power supply that employs a software switching system.
Capable to expand the system up to a maximum output of 40 kW by the master-slave parallel operation.
Communication functions for remote control also come standard with the product.
The all models can also receive three-phase 200 Vac and inputthree-phase 400 Vac input. In this manual, the three­phase 400 Vac input models are often simply referred to as “400 V input model.”
• Reduction of harmonic current and power transmission loss
The power-factor improvement circuit reduces the effects of harmonic currents on the input power line. It also suppresses the peak current and reduces the power transmission loss.
• Master-Slave parallel operation
Up to five power supplies can be connected in parallel to expand the output power to 40 kW. (You can expand the output pow two PAT850-9.4T power supplies in parallel.)
• Output limit function
Yo u can set the upper limit of current and voltage that is applied when setting the output. This function is used to prevent setting inappropriate value by mistake.
• Remote interface
Equipped with RS232C as standard. You can select the GPIB, USB or LAN interface as a factory option. The remote interface complies with IEEE 488.2 std 1992 and SCPI Specification 1999.0. Because the LAN interface complies with the LXI standard, the construction of a highly cost-effective system is possible.
•High efficiency and low noise
The PAT is a highly efficient, low-noise power supply that employs a software switching system. High power conversion efficiency has reduced the rise in the internal temperature and has contributed to the product’s compact and light design.
• Downsized input distribution device
The input distribution device (breaker) can be downsized, because the built-in power-factor improvement circ reduces the required input current.
• Preset memory function of settings
Up to three output setting presets (combination of current and voltage) can be saved. Yo u can simply select a preset to set the output without having to set the voltage and current every time you use the PAT.
• Output on/off delay function
Yo u can set a delay until the output is actually turned on or off after turning the OUTPUT switch on or off. For example, this feature is useful if you want to turn the output on/off by setting a time offset according to the load characteristics.

The PAT stores the panel settings (excluding output on/off condition) immediately before the POWER switch is turned off. For these items, the PAT starts up using the settings that existed when the POWER switch was turned off the last time.
If the POWER switch is turned off immediately after changing the settings, the last settings may not be stored.
When turning the POWER switch off and then back on, allow at least 10
seconds (40 seconds for 400 V input model) after the fan stops. Repeated ON/OFF of the POWER switch at short intervals can cause damage to the inrush current limiter or shorten the service life of the POWER switch and the internal input fuse.

Connecting the Load

This chapter describes the consideration to be given to the load, explains how to connect the load wires, and explains how to connect to the output terminals.

2.1 Load Considerations

Note that the output will become unstable if the following types of loads are connected.
Load with peaks and pulse-shaped current
The PAT indicates only mean values. Even when the indicated value is less than the preset current value, the peak values may actually exceed the preset current value. If this happens, the PAT is instantaneously put into constant-current operation mode, and the output voltage drops accordingly. For these types of loads, you must increase the preset current value or increase the current capacity.

Fig.2-1 Load current with peaks Fig.2-2 Pulse-shaped load current
Load that generates reverse current to the power supply
The PAT cannot absorb reverse current from the load. Therefore, if a regenerative load (such as an inverter, converter, or transformer) is connected, the output voltage increases and becomes unstable. For these types of loads, connect a resistor RD as shown in Fig.2-3 to bypass the reverse current. However, the amount of current to the load decreases by max. reverse current I

CAUTION
Use a resistor with sufficient rated power for resistor RD.
If a resistor with insufficient rated power for the circuit is used, resistor RD
may burn out.
Load with accumulated energy
Connecting a load with accumulated energy, such as a battery, to the PAT may cause current to flow from the load to the internal circuit of the PAT. This current may damage the PAT or reduce the life of the battery. For this type of loads, connect a reverse-current-prevention diode (DRP) between the PAT and the load in series as shown in
Fig.2-4.
This cannot be used in conjunction with remote sensing.

Use a reverse-current-prevention diode (DRP) complied to the following
references.
Reverse voltage withstand capacity :
At least twice the rated output voltage of the PAT.
Forward current capacity :
Three to ten times the rated output current of the PAT.
A diode with small loss.
•Be sure to take into account the heat generated by reverse-current-
prevention diode D
RP. Reverse-current-prevention diode DRP may burn out
with inadequate heat dissipation.

2.2 Load Cable

W ARNING
To prevent the possibility of fire.
Use a load cable with sufficient current capacity with respect to the rated output current of the PAT.
The output terminal and its area nearby gets very high temperature, use the cable with sufficient heat resistance higher than 85 °C of the covering materials.
Possible electric shock.
Use a load cable with a higher voltage rating than the isolation voltage of the PAT. For the isolation voltage of each model, see Chapter 8, “Specifications.”
Current capacity of the load cable
If their current rating exceeds the maximum rated output current, the cable will remain intact even if the load is short-circuited. Load cables must be rated to carry the maximum rated output current of the PAT.
Allowable current of the cable dependent on the maximum allowable
temperature of the cable insulation
The cable temperature is determined by a current-caused resistance loss, ambient temperature, and thermal resistance to the outside. capacity of current that can flow through a heat-resistant PVC wire (single wire)
having a maximum allowable temperature of 60 °C when the wire is stretched horizontally in the air at an ambient temperature of 30 °C. If the condition is such
that PVC wires with lower heat-resistant temperature are used, the ambient temperature exceeds 30 °C, or the wires are bundled resulting in low heat radiation,
the current capacity needs to be reduced.

Connecting the Load
When connecting wires that have the same heat-resistant temperature, more current can flow by separating the wires to make heat radiation as great as possible. However, installing the + (pos.) and - (neg.) output wires of the load cable side by side or bundling them together is more effective against unwanted noise. The Kikusui-recommended currents shown in
Table 2- 1 are allowable current values that have been reduced in consideration of the potential bundling of load cables. Use these values as a guideline when connecting load cables.
Limitations of the sensing function
All wires have resistance. The voltage drop in wires becomes greater as the wire becomes longer or the current becomes larger. This results in the voltage applied at the load end to be smaller. The PAT has a sensing function that compensates for this voltage drop up to approximately 0.6 V for a single line. If the voltage drop exceeds this level, wires having a greater sectional area should be used.
