High-precision fully automated communication pressurizer model: zpj6-svc-2000va library: m305925
Technical characteristics
1. Output capacity
When grid voltage is less than 198v, the output capacity of the pressurer is reduced; when the output voltage is selected
At 110v, the pressurer output cannot exceed 50% of the rated capacity; its output capacity and input
The voltage relationship is shown in figure 1。
Overload capacity
Special case for emergency use when the input voltager's voltage varies between 198 and 250 v
The excess capacity is shown in table 1
(p - output capacity; pc - rated output capacity; u - input voltage)
3, 220v, 110v voltage simultaneous output function: svc-3000va (single phase) with two
The kind of voltage is also output function。
4. Municipal direct power supply: when grid voltage is stable, municipal electricity is available to reduce power loss
Direct power supply。
Svc-2000va (single-phase) and above, with market power
The svc-1. 5kva (type iii) and above bring the electrical function to the market。
5. Overload or short-circuit protection: single-phase 1500va and the following for overloading or short-circuit protection by smelting machines
All other specifications are provided with circuit breakers for overloading or short circuit protection。
Wind dissipation function: the internal wind machine is controlled by a temperature control device, and when sampled at 55°c
Wind machines turn heat; vice versa, wind machines stop working。
