Rack mount High Voltage Power Supplies HARS series

Flexible Current Limit and Protection: CC Control & OCP turn-off SYSTEM

The HARS series offers both Constant Current (CC) control and Overcurrent Protection (OCP). By configuring the set points for each, you can define the desired behavior. Set the CC level to actively limit the current by voltage droop, or set the OCP threshold to cut off the output completely for protection. This dual-functionality provides flexible and reliable control over the output current.

Protection by Arc Trip

Arc discharge count Protection

The HARS series makes it easy to protect your power supplies with its advanced arc count & monitoring function.

There are two methods to set the output stop:

• (1) Arc Protect Count:
  The output is turned off when the output current surpasses the arc count limit.

  

  Maximum arc count: 9999

• (2) Arc Protect Count and Time:
  The output is turned off when the output current surpasses the arc count limit within a defined time frame.

  

  Maximum arc count: 999
  Maximum of arc protection enabling time: 59 m 59 s

Pulse Ramp Function

Set pulse/ramp operation output without a Computer control

* If the set time is shorter than the rising time: Tr or the falling time: Tf of the main unit, the output cannot follow the set value.

A. Pulse (Step) Sequence Function

---

The Sequence function lets you generate complex voltage and current patterns by automatically cycling through settings stored in memories a, b, and c. You can run the sequence continuously or for a specified number of cycles. By setting the duration of any step (a, b, c, or off) to 0.0, you can easily skip steps to create custom test patterns. This flexibility is ideal for product evaluation and reliability testing.

B. Ramp Function

---

The Ramp function provides linear control to gradually increase the output to a set voltage/current, or decrease it to zero. This feature is useful for applications that require a slow power-up or power-down.
* The ramp operation can be applied to: Voltage and Current, Voltage Only, or Current Only.

C. Combined Sequence and Ramp

---

For advanced control, the Sequence and Ramp functions can be used together. This allows you to create complex profiles by smoothly ramping the voltage and/or current between the discrete steps defined in memories a, b, and c. The entire waveform can be run continuously or for a pre-set number of cycles, making it a powerful tool for various testing scenarios.

External analog remote control

• External output ON/OFF
  The output can be turned ON/OFF by relay or TTL signal.

• Remote/Local change
  As for the output voltage control, output current control, overvoltage protection, and overcurrent protection, the remote/local mode can be individually switched by relay or TTL signal.

• Output monitor (Voltage, Current)

• Output control (Voltage, Current, Overvoltage protection, Overcurrent protection)

• Status output

-LF

Floating Ground

For measuring the current in load. (Able to withstand voltage of 50 Vdc)

For devices that connect to a Remote control connector (TB1), -LF requires floating ground.

*This option cannot be used to float the high voltage power supply itself.

-LGob^*

Optical interface port

Available in selecting optional an optical interface port
With optical communication, isolation control is performed. As complete isolation is performed via optical fiber, this enables the prevention of erroneous operations involved with transient phenomenon caused by surges, inductive lightning, external noise, etc.

Separate adapter (CO/USB series) is required for control via digital interface.

-LRs^*

RS-232C/RS-485 interface port

(only 10 kV or less models)
Using RS-232C/RS-485 communications, output controlling and operation status monitoring of these devices can be performed.

-L(230V1P)

Single-phase input

(2000 W or more models)

-L(0m)

Without output cable

Output cable not provided.

If you require a cable longer than 2.5 meters, please select this option and purchase an output cable separately.
