Design Features

Constant Output Power
In constant output power mode, the voltage and current range is switched
automatically to maximize the voltage and current without sacrificing the supply’s output
power. This mode enables the supply to provide a higher output voltage at lower current
and a higher output current at lower voltage. Compared to the traditional rectangular
output range of most supplies, the SPS5000X series power supply provides a wider
voltage and current output range, which greatly increases the utilization of the power
supply.

Adjustable Output Voltage, Current up/down Slew Rate
The SPS5000X series supports custom setting of the rise/fall slew rate ofvoltage/current to verify the performance of the object under test as thevoltage/current changes. This feature can effectively prevent the damage caused byinrush current to the DUT in applications such as the testing of capacitive current
absorbing devices.

CV/CC Priority Mode
When the SPS5000X series power supply is set to CC priority mode, at the power
output-on stage, it is able to operate under CC priority to limit the inrush current spikeand overshoot voltage effectively when the power output is turned on.
In CV priority mode, the output voltage reaches the set voltage value quickly. In some
applications, such as LED testing, when the power output is started, the surge current
and overshoot voltage will appear when the voltage reaches the on-state voltage of theLEDs.

Adjustable Output Resistance
The SPS5000X series power supply supports software - defined settings for output
internal resistance. It can be used as an internal resistance in series with the positive
output pole. At this point, the power supply is equivalent to the power supply containing
internal resistance, such as lead-acid battery or lithium battery.

Built-in Discharge Circuit
SPS5000X series power supply is designed with a discharge circuit in parallel withthe output terminal, which can be equivalent to a parallel resistance. When the power isturned off and the load is disconnected, the discharge circuit will discharge the power inthe output filter capacitor. Without the discharge circuit, the output capacitance will remain
charged, which may pose a dangerous voltage at the output terminals for a period of time.
The discharge circuit can also be used to adjust the voltage down slew rate. This function
is enabled in the menu by the user.

By editing the single-step setting value, duration, and slew rate, the List function can
generate multiple complex sequences to meet complex test requirements. The user canedit the sequence by 50 steps natively or import the List sequence file via USB for
multi-step running.
The minimum precision of delay time is 1ms. The minimum running time is 1 second.

External Analog Control
Four operating modes can be implemented using the analog port on the back of theunit; voltage-controlled voltage, voltage-controlled current, resistance-controlled voltage,
and resistance-controlled current. In external voltage control mode, when the terminal isconnected with adjustable voltage of 0-10V, it can be used to adjust the output from 0 to
full range (10V corresponds to the voltage or current value of the full range of the power
supply).

Series and Parallel Function
Multiple single-channel SPS5000X series modules can be connected in series (2 unitsmax.) or in parallel (3 units max), to increase the total output voltage, current and power.
The SPS5000X series offers a highly flexible configuration concept to provide high power
density that meets the needs of many applications.
(Typically, outputs of the supply float so the negative terminals are not connected tochassis ground. The negative terminals can also be connected to chassis ground.)Master unit

Multiple Policy Protection Patterns
The protection functions of the power supply include over current protection (OCP),
over voltage protection (OVP) and over temperature protection (OTP). If protection occurs,
the power supply will turn off the output and enter protection mode. Protection can bereleased by pressing the Esc key for at least 2 seconds. Upon entering the Limited powerprotection (LPP), the system will start the power limitation mode, the maximum output
power is about 105% of the rated power.

Save/Recall Setting Parameters
The power supply allows users to save multiple types of files to memory for later recall.
The power supply provides a non-volatile internal memory and an external memory via theUSB port with a user provided USB memory device.
