800V variable DC power supplies provide adjustable 0–800V output for laboratory bench testing and equipment development. Choose from 1A, 3A and 6A current ranges, two-knob or coarse/fine adjustment, and available communication options. Compare the 800V models and application requirements below, then select a product and configure your order.
800V DC Power Supply Model Comparison
| Model | Output ranges | Front-panel adjustment | Remote control | Order online |
|---|---|---|---|---|
| eTM-8001C | 0–800V / 0–1A | Two knobs | Programmable; optional communication interface | View product |
| eTM-8003C | 0–800V / 0–3A | Two knobs | Programmable; optional communication interface | View product |
| eTM-8006 | 0–800V / 0–6A | Four-knob coarse/fine | Optional interface; page lists On/Off/Read | View product |
| eTM-8006C | 0–800V / 0–6A | Two knobs | Programmable; optional communication interface | View product |
These four models cover different current and control requirements within the range shown above. Select continuous output power and AC input for your actual operating points. Optional communication interfaces are selected on the product page; a matching voltage/current range does not mean identical remote-control functions.
Features of ETOMMENS 800V Bench Power Supplies
- Adjustable voltage and current: continuously adjustable 0–800V output covers different DC input levels on one bench. Choose a 1A, 3A or 6A range for the current your load needs.
- Automatic CV/CC operation: regulate voltage while the load remains below the set current limit. At the limit, constant-current operation can reduce voltage to hold the selected current.
- Manual control choices: eTM-8006 has coarse/fine voltage and current adjustment for large changes followed by small setting adjustments. The C models use a two-knob layout and list output switch control.
- Protective functions: the four compared models list overvoltage, overcurrent, overpower, overtemperature and short-circuit protection. Match the settings and wiring to the connected equipment.

High-voltage circuits with current demand within 1A
For a circuit or module requiring controlled high-voltage DC at modest current, eTM-8001C provides the 0–1A range. Adjustable output lets you test different voltage settings without selecting a higher-current model solely for its larger headline rating. Include startup demand when checking whether the 1A range covers your circuit.
DC-DC converter development and tests within 3A
Choose by the converter’s input-voltage range and input current, rather than its output current. Compare eTM-8003C for requirements above 1A and within 3A. The adjustable 0–800V range covers lower DC input test points such as 400V and 600V, within the converter’s limits. A test at 800V and 3A requires 2400W of load power; choose a configuration that supports that working point continuously.
Higher-current powered tests within 6A
Compare eTM-8006 and eTM-8006C when the load needs more than 3A and up to 6A. For example, a 600V, 5A test requires 3000W. Choose eTM-8006 for four-knob coarse/fine adjustment during repeated manual tests, or compare eTM-8006C for its two-knob layout and programmable communication options.
Computer-controlled voltage and current sequences
The C-model pages describe programmable communication; eTM-8006C offers RS232, RS485, USB and RS232 plus analogue-control options. Select the required interface and check the supported commands for your software. The eTM-8006 page lists On/Off/Read, so its interface should not be assumed to provide the same voltage/current setting commands as the C models.
800V Bench Power Supply FAQs
Can one 800V supply cover 400V and 600V tests?
Yes. The compared models have adjustable 0–800V output. Choose the current range and continuous output capability for each test point: 400V at 2A requires 800W, while 600V at 5A requires 3000W. These are load-power calculations, not additional model power ratings.
Can I choose 110V AC input for an 800V, 6A load?
No for the listed 110–130V option on eTM-8006C: that option is limited to output power of 1200W or less. An 800V, 6A load requires 4800W. Choose an AC-input and output configuration that supports the required continuous power.
Will the supply hold the set voltage when the load reaches the current limit?
In CV mode, voltage is regulated and current follows the load. Once the current limit is reached, CC mode regulates current and voltage can decrease. Include startup current in model selection if the load must start without entering current limit.
Does a four-digit display mean higher output accuracy?
No. Display resolution and output accuracy are different specifications. Compare setting accuracy, ripple/noise and regulation under the conditions stated for the exact model when these affect your test.
Can these supplies absorb power returned by my load?
If your battery, converter or other load can feed power back toward the supply, the test setup needs to handle that returned energy. Contact us with the operating voltage, current and test sequence so we can help assess the required configuration. Do not assume a standard bench supply can absorb returned power.
