• Power-factor improvement circuit The power-factor improvement circuit reduces the effects of har-
monic currents on the power line.
• High efficiency The high power conversion efficiency reduces the cost of power
and the cost of heat radiation design during system configura­tion.
• Communication functions Equipped with a digital remote control function through TP-BUS
(Twist Pair-BUS) communication (The total length of TP-BUS is 200 m). By combining with Kikusui’s PIA4800 Series Power Sup­ply Controller, systemization for applications such as an auto­matic tester is possible.
• Master-slave operation Output voltage or output current can be expanded by connect-
ing multiple power supplies of the same model in series (only on the L type) or in parallel. This feature allows slave units to be controlled from a single master unit.

the extended operating area. The extended operating area is valid only on the L type.
If the PWR is configured in way that satisfies the equation output voltage x output current ≤ rated output power, the PWR operates as a conventional constant voltage/current power supply.
If the PWR is configured in a way that satisfies the equation output voltage x output current > rated output voltage, the actual output is limited by the power limit (approx. 105% of the rated output power) and the output voltage or output current varies depending on the load value.

Turning the Power On
Turn the power on without the load connected.
CAUTION
The CONFIG parameters can be set so that the output is au­tomatically turned on when the POWER switch is turned on. When this function is enabled, the PWR powers up with the output turned on even if the output was off when the PWR was turned off the last time. There is a possibility that a load may break, if you connect a different load and turn the POW­ER and output on simultaneously without changing the OVP and OCP settings to appropriate values.
Turning the Power switch on
Check that the POWER switch is turned off.

Inrush current
An inrush current flows when the POWER switch is turned on. If you are planning to use several PWRs and turn on their POWER switch­es simultaneously, check that the AC power line or the switchboard has sufficient capacity. For the inrush current of each model, see “Specifications” of the user’s manual on the accompanied CD­ROM.
Turning the POWER switch off
Push the (○) side of the POWER switch to turn the PWR off. The PWR stores the panel settings (excluding output on/off condi-
tion) immediately before the POWER switch is turned off. For these items, the PWR 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.
CAUTION
When turning the POWER switch off and then back on, allow at least 10 seconds after the panel display lights out. Repeat­ed on/off of the POWER switch at short intervals can cause damage to the inrush current limiter and shorten the service life of the POWER switch and internal input fuse.

Load Considerations
Load current with peaks
Ammeter reading (average value)
Note that the output will become unstable if the following types of loads are connected.
Load current with peaks and pulse-shaped load
current
The PWR indicates 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 PWR 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.
Preset constant current value
Ammeter reading (average value)
Preset constant current value
Pulse-shaped load current
Load that generates reverse current to the power
supply
The PWR 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 figure below bypass the reverse current. However, the amount of current to the load decreases by Irp.
CAUTION
Select a resistor with sufcient rated power for RD. If a resis­tor with insufcient rated power for the circuit is used, RD may
burn out.

Load with accumulated energy
Connecting a load with accumulated energy, such as a battery, to the PWR may cause current to flow from the load to the internal cir­cuit of the PWR. This current may damage the PWR or degrade the service life of the load.
For this type of loads, connect a reverse-current-prevention diode (DRP) between the PWR and the load in series.
CAUTION
• To protect the load and the PWR, select a DRP that com­plies with the following conditions.
Reverse voltage withstand capacity of at least twice the rated output voltage of the PWR.
Forward current capacity that is 3 to 10 times the rated out­put current of the PWR.
A diode with small loss.
• Be sure to take into account the heat generated by DRP. DRP may burn out without adequate heat dissipation.

Cannot be used in combination with remote sensing.

Load Wire
Note the following points concerning the wire used to connect the load.
WARNING
• To prevent re, use a load wire with sufcient current capacity with respect to the rated output current of the power supply.
• Possible electric shock. Use a load wire with a higher voltage rating than the isolation voltage of the PWR. For the isolation voltage of each model, see “Speci­cations” of the user's manual on the accompanied CD­ROM.
Current capacity of the load wire
If the current rating exceeds the maximum rated output current, the wire will remain intact even if the load is short-circuited. Load wires must be rated to carry the maximum rated output current of the PWR.
Allowable current of the wire dependent on the
maximum allowable temperature of the cable insu­lation
The wire temperature is determined by a current-caused resistance loss, ambient temperature, and thermal resistance to the outside. Table shows the allowable capacity of current that can flow through a heat-resistant PVC wire (single wire) having a maximum allowable temperature of 60 ºC when the wire is stretched horizontally in the air at an ambient temperature of 30 ºC. If the condition is such that PVC wires with lower heat-resistant temperature are used, ambient temperature exceeds 30 ºC, or the wires are bundled resulting in low heat radiation, the current capacity needs to be reduced.
Taking measures against noise
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 side by side or bundling them together is more effective against unwanted noise. The Kikusui-recommended cur­rents shown in Table are allowable current values that have been reduced in consideration of the potential bundling of load wires. Use these values as a guideline when connecting load cables.
14 PWR Series Setup Guide
Page 15
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 PWR 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.
