The ZX-S Series is the Switching DC Constant Voltage/Constant Current Power Supply
capable of changing from zero-volt and zero-ampere.
By applying the Zoom method, an extension ratio of 8 times is possible within the range of the
rated output power. (See Note 1)
・The ZX-S series allows the use of both the Constant Voltage and Constant Current modes,
along with the ability to be able to freely set the power from zero to full scale.
・The ZX-S series, with full digital control, also grants settings with superior accurate
reproduction.
Note１． Zoom method is the ability to output a high voltage in areas with low current, and high current in areas
with low voltage, while maintaining the output range for the rated power, as shown in the diagram below.

Features
✧Multi-Functional Zoom Power Supply
Able to handle any combination of voltage and current.
Perfect for experiments requiring both voltage and current.
✧Standard Equipment of LAN/Serial Communication
Port
By the equipment of multi-drop communication port, LAN
port and RS-485 port is capable to control up to 31units of
ZX-S Series.
※For multiple connections, the KXC-300 cable (sold
separately) is required.
✧Improved Parallel Operation （New Master/Slave）
CV transient recovery properties will not degrade, even when
increasing the number of parallel units, due to both the
master and slave units being controlled simultaneous.
✧Useful Functions
□Memory
Saves and loads 3 set panel settings
Perform voltage variation tests and other tests
effortlessly.
□Variable Slew Rate
Changes the slew rate for the rising and falling of the
voltage/current.
□Startup Mode Selection
Equipped with a CC Priority Mode for loads with nonlinear
V-I characteristics similar to diodes, this function is
capable of preventing current overshoot when output is
ON.
□Sequential ＯＮ/ＯＦＦ
Sets the order outputs are toggled ON/OFF through a
multi-connection cable.
✧Protection Functions

Protection, Over Current Protection, Over Power Protection,
Over Heating Protection, Excessive Input Current Protection,
etc
✧External Analog Control（ZX-S Series Type-LAN）
Able to control ON-OFF output with external contact points,
and voltages and currents based on external DC voltage (0
～10Ｖ) and external resistance (0～∞ or 0～10ｋΩ)
※Full-scale and offset adjustments can be performed with
the front panel dials.
✧Analog Monitor （ZX-S Series Type-LAN）
Outputs the output voltage and output current with 0～10Ｖ
DC.
※Not suited for monitoring transient voltage/current
waveforms.
✧Status/Alarm Output（ZX-S Series Type-LAN）
Outputs an alarm or operation status with a photocoupler
output (open collector) insulated from outputs and the earth.
✧Variable Internal Resistance
(ZX-S Series Type-LAN)
Intentionally generates voltage drop through load current
when running in constant voltage mode.
With this function, the power supply is capable of
approximating an internal resistance of chemical batteries
(during electric discharge) and I-V characteristics of
solar/fuel cells.
※Restricted to direct current operations. Not suited for
approximating transient effects.

Connecting the Power Supply
This product operates on a ８５Ｖ～２５０Ｖ and ４５Ｈｚ～６５Ｈｚ single-phase AC power supply.
The maximum input current during rated output is approximately 7A when the AC power supply’s voltage
is ８５Ｖ.
To ensure proper and safe use of this produce, please observe the following.
Danger
Ground the green cord when using the 2P-3P adapter.
Mandatory
A noise filter is built into the device to prevent EMI (Electromagnetic Interference).
Due to this, even the slightest amount of leaked current may result in electric shock if not
Mandatory properly grounded.
For safety reasons, please ground the device.
Caution
Please use input power within ranges of ８５Ｖ～２５０Ｖ and ４５Ｈｚ～６５Ｈｚ (single-phase).
Mandatory Nominal Power Supply Voltage is displayed near the rear panel inlet.
Please connect to a power supply capable of providing the maximum electric power consumption.
Mandatory
Please use the input power cable included with the product.
Do not use the input power cable with any other products.

・Twisting wires can minimize the ripple and noise at
the load terminal.
・The noise level can be minimized smaller than the
standard value by connecting the C1 and C2 close to
the load terminal.
Using a small, high-frequency impedance for C1 and
C2, cut the lead wire as short as possible and
connect.
Ｃ１：Electrolytic Capacitor １00～1000μF
Ｃ２：Film Capacitor １～10μＦ

Danger
Verify that the main power supply for the power supply is turned off when connecting loads.
Mandatory
Do not wire loads when voltage is being outputted from the power supply.
Prohibited
Caution
Use wires with sufficient cross section areas for load currents.
Mandatory Ex.）See Appendix Load Current vs Cross section areas.
Attach crimp-style terminals to wires and securely fasten.
Mandatory If insecurely fastened, wires may become deformed or burn out due to the generated heat at
connection points.

Attaching the Output Terminal Cover
１．Hook and attach one terminal cover (both covers are identical in shape) on the upper grooves of the Output
Terminal platform.
２．Attach the support rod to the remaining terminal cover (inserting it into the center part of the cover) and
affix the rod in place by screwing an M3x6mm into it from the bottom of the cover.
３．Hook the terminal cover (with attached support post) on the lower grooves of the Output Terminal platform,
then raise and snap the terminal cover in place with the upper-half.
M3 Screw Hole
４．Fasten a M3×6mm screw from above.

基本的な使い方
Startup Display
Once power is turned on (POWER switch pushed to ON), the power supply model will be displayed in the top Number
Display and the firmware version and number of parallel connected devices will be displayed in the bottom Number
Display.
If there is a disagreement in the number of parallel connected devices (if there is a difference
between the number of parallel devices used previously and now), the error code “E011”will be
displayed in the top Number Display and the number of detected devices will be displayed blinking
in the bottom display. After confirming the number of parallel devices, hold down the FUNC. key
for more 2 seconds to approve and proceed to measurement display mode.
