About tthis machine
The HX-S-G2 Series is the Switching DC Constant Voltage/Constant Current Power Supply capable of changing
from zero-volt and zero-ampere.
●The HX-S-G2 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 HX-S-G2 series, with full digital control, also grants settings with superior accurate reproduction.

Features
Improved Parallel Operation (New Master/Slave)
Up to 10 HX-S-G2 power supplies of the same voltage output type
(maximum capacity 120 kW) can be operated in parallel.
Constant voltage transient recovery properties will not degrade, even
when increasing the number of parallel units, due to the new master-
slave method.
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 units of supported
models.
* Special cable (T485-****: * is the code that indicates length.)
Supported models (as of July, 2012)
ZX Series
FK II Series
HX II Series
Useful Functions
Memory
Saving and loading can be done for 3 sets of panel setting
status. Tests such as voltage fluctuation test can be
conducted by easy operation.
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.
[Output Voltage/Current Range]

Sequential ON/OFF
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 Heating Protection,
Excessive Input Current Protection, etc
External Analog Control
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
Outputs the output voltage and output current with 0~10V DC.
*Not suited for monitoring transient voltage/current waveforms.
Status Alarm Output
Outputs an alarm or operation status with a photocoupler output
(open collector) insulated from outputs and the earth.
Variable Internal Resistance
This function intentionally generates a voltage drop due to 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.
