Compare DC and AC backup for your equipment. Match output voltage, load demand and battery configuration before planning a sample evaluation.
Bring the device input, connector and required backup period. We will help frame the configuration and documentation review.
Manufacturer reference photographs; identifying and generic rating labels edited. Confirm the selected configuration.
Compare DC and AC output, power limits and battery options. Choose a reference to review its full specification and prepare an enquiry.

Reference 4B(H)
4B(H) reference AC–AC mini UPS with listed maximum power of 300 W and a 14.8 V, 6.8 Ah lithium-ion battery.
Basic, L and H references have different power or battery information. Voltage options require an ordered configuration.
On narrow screens, scroll the table sideways to compare all columns.
| Reference | Output | Power limit | Battery | Calculated nominal energy |
|---|---|---|---|---|
| 4D | 12 VDC ±2% | 60 W Rated power | Confirm battery configuration | Battery details to confirm |
| 4D(L) | 12 VDC ±2% | 60 W Rated power | 14.8 V · Up to 3.4 Ah · Lithium-ion | Up to 50.32 Wh |
| 4D(H) | 12 VDC ±2% | 60 W Rated power | 14.8 V · Up to 6.8 Ah · Lithium-ion | Up to 100.64 Wh |
| 4B | AC · confirm voltage option | 300 W / 500 VA Power configuration | Confirm battery configuration | Battery details to confirm |
| 4B(L) | AC · confirm voltage option | 150 W Maximum power | 14.8 V · 3.4 Ah · Lithium-ion | 50.32 Wh |
| 4B(H) | AC · confirm voltage option | 300 W Maximum power | 14.8 V · 6.8 Ah · Lithium-ion | 100.64 Wh |
Nominal Wh is calculated from the documented battery voltage × capacity, not measured usable energy or runtime. An “Up to” capacity gives an upper-bound calculation. Confirm the battery nameplate Wh and selected configuration.
For the basic 4D, request the current battery type, capacity and confirmation of the listed 1.314 kg weight before comparing it with L/H versions.
Portable operation and timed shutdown may suit a different brief. Request current electrical specifications before shortlisting these functional references.
4M mobile mini UPS reference with operation without AC startup, ON/OFF control and a listed Ni-MH battery. Electrical ratings require current documentation.
Request 4M documentation
4T timed mini UPS reference for preset backup operation followed by shutdown, with a listed Ni-MH battery. Timing and electrical configuration require review.
Request 4T documentationUse these application briefs to define the electrical match. They are starting points for review, not verified compatibility or runtime claims.
For devices specified for 12 VDC input, compare the 4D references against the load current, connector size and polarity. Include startup demand and the backup duration you need to test.
List every powered device, its voltage, total continuous and startup demand, cable run and required input-loss response. Confirm any safety-related operating requirements for the complete installation.
Identify the terminal and peripherals, AC or DC supply, W and VA demand where available, and the intended shutdown process. Agree a sample test at the actual combined load.
Start with the equipment and its operating conditions. Open questions can travel with the brief.
Prepare Your UPS EnquiryRequest the selected model’s documents for your destination market, then agree the load test, evaluation configuration and sample terms.
Request UPS DocumentationRated and maximum output describe different limits. Backup duration depends on the battery, load, operating conditions and cutoff behaviour. Validate it at the intended load.
Published output-voltage options are available configurations, not an automatic voltage range in one unit. Confirm voltage, frequency where relevant, connector and polarity together.
Request the current electrical specification, battery information and available certification or test records for the exact model and destination market. Agree the evaluation configuration and acceptance criteria before purchase.
Ask for the actual battery nameplate Wh, UN 38.3 test summary and safety data sheet (SDS/MSDS), then confirm carrier and route acceptance before arranging samples. The calculated nominal Wh in the comparison table does not determine a shipment classification or substitute for the selected battery’s documents.
Bring a drawing, existing power supply or installation brief. Each requested change needs a supplier feasibility and documentation review; none is a standard option unless confirmed for the selected model.
