N32100 series overview
The N32100 series comprises programmable high-voltage DC power supplies available as positive-output models and separate negative-output variants. Models are offered with rated voltages of 3 kV, 4 kV, 5 kV, 6 kV, 8 kV or 10 kV and output-power classes of 1 kW or 2.5 kW. Depending on the model, maximum output current ranges from 150 mA to 1 A. The units operate as single-polarity DC sources without controlled bidirectional sink operation. Their wide-range output characteristic provides several voltage and current operating points within the applicable power limit. A dedicated low-voltage mode reduces ripple at lower output levels. Every model includes a 4.3-inch colour display, a compact 2U enclosure and standard LAN, RS232, RS485 and CAN communication. Typical fields include power semiconductors, high-voltage components, particle accelerators and high-energy physics experiments.
Key benefits
Wide output characteristic
Each model provides multiple voltage and current combinations within its power envelope, reducing the number of separate supplies required.
Selectable polarity variant
Positive standard models are complemented by dedicated NE versions with fixed negative output polarity.
Fast voltage establishment
A specified voltage rise time of no more than 25 ms supports tests requiring short voltage-establishment periods.
Optimised low-voltage output
The dedicated low-voltage mode reduces ripple when a high-voltage model is operated at comparatively low output levels.
Extensive sequence capacity
Up to ten sequence files with 1,000 steps each support reproducible voltage, current and timing profiles.
System-ready control
Multiple digital interfaces and optional analogue and I/O signals simplify integration into laboratory, production and ATE systems.
Operating principle of the high-voltage DC power supply
Constant-voltage operation
In CV operation, the unit regulates the output voltage to the programmed setpoint. The current setting defines the maximum permitted output current.
Current-limited operation
When load current reaches the programmed limit, regulation transfers to CC operation and maintains a constant output current.
Positive and negative models:
Standard versions provide a positive output. The “-NE” suffix identifies a separately manufactured negative-output version. A single unit does not change between positive and negative polarity.
CV/CC priority allows the startup and transition behaviour to be adapted to the device under test. CV priority focuses on controlled voltage regulation with low voltage overshoot. CC priority is intended for low-impedance or capacitive devices where controlled current rise is the main requirement.
Models and technical specifications
The series is divided into two power groups. N32110 models provide up to 1 kW, while N32125 models provide up to 2.5 kW. These ratings apply with a 200 to 240 VAC supply. At 100 to 140 VAC, the listed output ratings are 500 W and 1,250 W respectively.
| Positive model | Negative model | Output voltage | Maximum current | Power at 200–240 VAC |
|---|---|---|---|---|
| N32110-3k-M600 | N32110-3k-M600-NE | ±3 kV | 600 mA | 1 kW |
| N32110-4k-M400 | N32110-4k-M400-NE | ±4 kV | 400 mA | 1 kW |
| N32110-5k-M300 | N32110-5k-M300-NE | ±5 kV | 300 mA | 1 kW |
| N32110-6k-M250 | N32110-6k-M250-NE | ±6 kV | 250 mA | 1 kW |
| N32110-8k-M200 | N32110-8k-M200-NE | ±8 kV | 200 mA | 1 kW |
| N32110-10k-M150 | N32110-10k-M150-NE | ±10 kV | 150 mA | 1 kW |
| N32125-3k-A10 | N32125-3k-A10-NE | ±3 kV | 1 A | 2.5 kW |
| N32125-4k-M800 | N32125-4k-M800-NE | ±4 kV | 800 mA | 2.5 kW |
| N32125-5k-M600 | N32125-5k-M600-NE | ±5 kV | 600 mA | 2.5 kW |
| N32125-6k-M500 | N32125-6k-M500-NE | ±6 kV | 500 mA | 2.5 kW |
| N32125-8k-M350 | N32125-8k-M350-NE | ±8 kV | 350 mA | 2.5 kW |
| N32125-10k-M300 | N32125-10k-M300-NE | ±10 kV | 300 mA | 2.5 kW |
The ± symbol in the table combines two separate unit variants. Standard models provide positive output voltage, while the corresponding NE models provide negative output voltage.
Output characteristic and low-voltage mode
Available output power depends on the actual combination of voltage and current. Maximum current cannot therefore be used simultaneously with rated voltage at every operating point. Required voltage, current and power must be evaluated together when selecting a model.
Depending on the voltage class, the normal CV range begins at 15 V, 20 V, 25 V, 30 V, 40 V or 50 V and extends to rated voltage. The additional low-voltage mode covers a limited lower range and reduces available current to half of the model’s maximum current.
| Rated voltage | Normal CV range | Low-voltage range | Low-voltage current limit |
|---|---|---|---|
| 3 kV | 15 V to 3 kV | 15 V to 145 V | 50% of model current |
| 4 kV | 20 V to 4 kV | 20 V to 165 V | 50% of model current |
| 5 kV | 25 V to 5 kV | 25 V to 210 V | 50% of model current |
| 6 kV | 30 V to 6 kV | 30 V to 250 V | 50% of model current |
| 8 kV | 40 V to 8 kV | 40 V to 330 V | 50% of model current |
| 10 kV | 50 V to 10 kV | 50 V to 420 V | 50% of model current |
Dynamic and regulation performance
The dynamic specifications describe different processes and must not be treated as equivalent values. Voltage rise time defines how quickly output voltage is established. Transient recovery time describes the return of output voltage to the specified tolerance band following a load step.
| Parameter | Specification | Practical meaning |
|---|---|---|
| Voltage rise time | ≤25 ms | Specified both at no load and full load. |
| Transient recovery time | ≤2 ms | Recovery to within ±1% of rated voltage after a load step from 50% to 100% at full output voltage. |
| Full-load voltage fall time | ≤100 ms | Conservative series-wide value; individual models are specified at 80 ms. |
| No-load voltage fall time | ≤2 s or ≤15 s | Models up to 5 kV are specified at no more than 2 s; 6 kV to 10 kV models at no more than 15 s. |
| Communication response time | ≤5 ms | Response time for remote communication. |
| Voltage resolution | 100 mV | Programming and readback resolution of the listed models. |
| Current resolution | 10 µA | Programming and readback resolution of output current. |
| Line regulation | Voltage ≤0.01% F.S. Current ≤0.02% F.S. |
Output variation caused by changes in AC input voltage. |
| Load regulation | Voltage ≤0.03% F.S. Current ≤0.05% F.S. |
Output variation caused by changing load conditions. |

Safe connection:
The enclosure must be reliably connected to protective earth. All output wiring must be completed while the unit is switched off. After power-down, wait at least 30 minutes before opening the enclosure.
Protection and safety functions
Overvoltage protection
A programmable threshold and configurable delay disable the output when the voltage limit is exceeded.
Overcurrent protection
Output is disabled when measured current remains above the programmed threshold for longer than the configured delay.
Overpower protection
Programmable power monitoring protects the DUT and supply against a sustained excess of the selected power limit.
Undervoltage protection
A configurable threshold with ready and delay times detects an unexpected reduction in terminal voltage.
Overtemperature protection
The output is automatically disabled if the internal temperature exceeds the permitted limit.
Foldback protection
The function monitors an unwanted transition into the selected CV or CC state and can disable output after a programmed delay.
The standard interlock circuit provides a hardware-related safety function beyond normal software control. Opening the circuit inhibits or terminates output operation.
