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.
Note󳞮󳞫 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.
󳗔Serial Communication Port Standardized System
Equipped with a multi-drop communication port, one RS-
232C or RS-485 port is capable of controlling up to 31
ZX-S Series units.
󳆽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 󳟌󳟋/󳟌󳟃󳟃
Sets the order outputs are toggled ON/OFF through a
multi-connection cable.
󳗔Protection Functions
Guards valuable loads and power supplies with Over Voltage
Protection, Over Current Protection, Over Power Protection,
Over Heating Protection, Excessive Input Current Protection,
etc
󳗔External Analog Control󳞥ZX-S Series Type-HA󳞦
Able to control ON-OFF output with external contact points,
and voltages and currents based on external DC voltage (0
󳟻10󳟓) and external resistance (0󳟻󳋓 or 0󳟻10󳟨󳁩)
󳆽Full-scale and offset adjustments can be performed with
the front panel dials.
󳗔Analog Monitor 󳞥ZX-S Series Type-HA󳞦
Outputs the output voltage and output current with 0󳟻10󳟓
DC.
󳆽Not suited for monitoring transient voltage/current
waveforms.
󳗔Status/Alarm Output󳞥ZX-S Series Type-HA󳞦
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-HA)
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.
