N3200 high-voltage DC power supply overview
The N3200 series provides positive or negative DC voltage for tests requiring high voltage and low current. Three single-channel models cover ±2,500 V, ±5,000 V and ±10,000 V. Maximum output currents are 10 mA, 5 mA and 2 mA, with power ratings of 25 W, 25 W and 20 W respectively. Voltage and current can be controlled locally, through a 0 to 10 V analogue input or digitally via LAN and RS232. A programmable sweep generates stepped voltage profiles. Analogue monitor outputs represent voltage and current for external acquisition systems. The compact half-rack, 2U enclosure supports benchtop use and 19-inch installation with an optional mounting kit. Typical applications include breakdown, insulation, leakage-current, high-resistance material and high-voltage component testing.
Key benefits
High output voltage
Three model ranges up to ±10,000 V support testing of insulation gaps, semiconductors and high-voltage components.
Fine current resolution
Series-wide current resolution of 0.1 µA supports sensitive leakage-current and high-resistance material measurements.
Low output noise
Models up to 5 kV achieve no more than 3 mV RMS with the filter for low-noise measurement setups.
Selectable polarity
The output can be configured for positive or negative high voltage and adjusted down to 0 V.
Compact half-rack enclosure
The 214 mm wide enclosure occupies half of a 19-inch rack and is also suitable for benchtop operation.
Fast communication
A 2 ms communication response supports short control and query cycles in automated test systems.
High-voltage source operating principle
The output operates as a programmable constant-voltage source with an adjustable current limit. Voltage and current are continuously read back and shown on the colour display. For tests requiring reverse polarity, the output direction can be changed while the output is disabled.
Regulated voltage operation
The setpoint is regulated within the selected positive or negative voltage range with an adjustable current limit.
Voltage and current limits
Programmable protection values disable the output when the defined voltage or current threshold is exceeded.
Positive and negative output
Selectable output polarity removes the need for an external high-voltage reversing switch in the test setup.
Stepped voltage profiles
The sweep increases voltage from the start to the end value using a programmable increment and time interval.
Output polarity may only be changed while the output is disabled. Switching polarity while high voltage is active is not permitted.
Models and technical specifications
Model selection is based on maximum voltage, output current and output power. All three versions provide one output channel and separate positive and negative voltage ranges.
| Model | Output voltage | Output current | Output power | Channels |
|---|---|---|---|---|
| N3225-2.5K-M010 | ±2,500 V | 10 mA | 25 W | 1 |
| N3225-5K-M005 | ±5,000 V | 5 mA | 25 W | 1 |
| N3225-10K-M002 | ±10,000 V | 2 mA | 20 W | 1 |
| Specification | N3225-2.5K-M010 | N3225-5K-M005 | N3225-10K-M002 |
|---|---|---|---|
| Negative voltage range | −2,500 to 0 V | −5,000 to 0 V | −10,000 to 0 V |
| Positive voltage range | 0 to +2,500 V | 0 to +5,000 V | 0 to +10,000 V |
| Voltage programming resolution | 0.1 V | 0.1 V | 1 V |
| Current programming resolution | 0.1 µA | 0.1 µA | 0.1 µA |
| Voltage readback resolution | 0.1 V | 0.1 V | 1 V |
| Current readback resolution | 0.1 µA | 0.1 µA | 0.1 µA |
Accuracy, stability and output noise
Programming and readback accuracy are specified separately for voltage and current. The models differ in output noise, while temperature coefficient and long-term stability are consistent across the series.
| Measurement specification | Series value |
|---|---|
| Voltage programming accuracy at 23 ± 5 °C | 0.01% + 0.05% of full scale |
| Current programming accuracy at 23 ± 5 °C | 0.02% + 0.05% of full scale |
| Voltage readback accuracy at 23 ± 5 °C | 0.01% + 0.05% of full scale |
| Current readback accuracy at 23 ± 5 °C | 0.02% + 0.05% of full scale |
| Programming and readback temperature coefficient | 50 ppm/°C |
| Long-term stability | ≤50 ppm/1,000 h |
| Voltage line regulation | ≤0.01% |
| Voltage load regulation | ≤0.01% |
| Model | Voltage ripple and noise with filter, 20 Hz to 20 MHz |
|---|---|
| N3225-2.5K-M010 | ≤15 mV peak-to-peak / ≤3 mV RMS |
| N3225-5K-M005 | ≤30 mV peak-to-peak / ≤3 mV RMS |
| N3225-10K-M002 | ≤50 mV peak-to-peak / ≤10 mV RMS |
Dynamic performance and regulation
Rise and fall times refer to a change between 10% and 90% of full scale or between 90% and 10%. The values depend on the model and load condition and must not be confused with the separately specified voltage settling time.
| Dynamic specification | N3225-2.5K-M010 | N3225-5K-M005 | N3225-10K-M002 |
|---|---|---|---|
| Voltage rise time, no load, 10 to 90% | ≤3 s | ≤4 s | ≤8 s |
| Voltage rise time, full load, 10 to 90% | ≤3 s | ≤4 s | ≤8 s |
| Voltage fall time, no load, 90 to 10% | ≤15 s | ≤30 s | ≤60 s |
| Voltage fall time, full load, 90 to 10% | ≤3 s | ≤3 s | ≤3 s |
| Voltage settling time | 3 s | 3 s | 3 s |
No-load voltage fall time increases significantly with the voltage range. Test timing should account for discharge of the connected DUT and the complete high-voltage setup.
