Note: The model with built-in battery and special voltage requirements can be customized according to the actual situation of the user, and a separate quotation will be provided.
① Overload alarm: Unplug non-essential single-phase loads, or replace with a larger capacity UPS; ② Phase loss alarm: Check 3-phase input wiring, repair loose or disconnected cables; ③ Battery low alarm: Charge continuously for 12 hours, replace aging batteries if the alarm persists; ④ Output voltage abnormal: Check output wiring, reset UPS (disconnect power and restart after 5 minutes); ⑤ Transformer overheating: Stop using immediately, check ventilation and load, contact after-sales for maintenance.
Its core function is to convert 3-phase mains power into stable 1-phase power, providing uninterrupted, pure power for single-phase critical loads while solving mains problems like voltage fluctuation, harmonic interference and power outage. Working principle: Adopt double conversion (AC-DC-AC) + low-frequency transformer design. When mains is normal, 3-phase AC is converted to DC to charge the battery, then DC is converted to 1-phase pure sine wave AC for load supply; when mains fails, it switches to battery power with 0ms transfer time,

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
