F1000-G Series
|
| F1000-G
series inverter is the latest product that Huifeng devote to
its users, which is designed on the base of HF-G series but
upgraded foe the purpose of general applications. This inverter
opens more than 130 function codes to users that can deduce
much more operations and codes. |

HF-K Series
|
| Presenting
the tempting advantage of stable performance, fine power saving
and specially functions, this series inverter is mainly applied
in air-conditioning units. I n practice, helped by the built-in
PID or PI adjuster, the closed loop system, composed of the
inverter and some sensors, may execute a marvelous self-adapting
control to the typical parameters, temperature, pressure flow
capacity and position. |

HF-W Series
|
| This
series inverter is designed for water supply at constant pressure.
It can switch to as many as 7 pumps, each of them enjoying free
manual or automatic control with no influence on the other pumps
working. The total number of pumps to be switched to can be
set from the keypad program, with setting value of 2~4 for multi-pump
circulation frequency conversion. Instantaneous impact on value
while being switched between pumps can be avoided through special
processing. All the individual pumps can operate under even
load through logic arrangement incase a certain pump may risk
erosion due to long idling. |
