Features:

TVR three-phase power monitor (also called phase protection, power relay) is 

used in alternating current 50 / 60Hz, rated voltage below 690V AC, and 

gives protection to over voltage, under voltage, phase failure, reverse phase, imbalance voltage of electromotors.

MCX main control unit is the part of interactive, to realize the function of query

parameter, setting, running administration, and web communication. 



Features: 

1) Operates under clew of LCD menu display in Chinese 

2) Plug and Play connecting net; extend I/O control board online; 

    extend MCX display unit online 

3) Self-identifies the module of connecting net; multi-option of running 

    mode 

4) Blur energy control, multi-compressor balanced running, sets the 

    number of compressor of connecting net online 

5) Self-diagnoses fault and protection; manual reset while no-fault 

6) Intelligent defrost; makes the statistic of output power automatically 

    while defrost manually, records manual starting and closing of all 

    units 

7) Inspection to defrost; can switch to the normal running process 

    completely and quickly 

8) Memorizes running status and clock of system while break electricity 

9) Over time limit; reminds operator before running time limit 

10) Starts and closes with one key; remote control switch 

11) Multiple password protection 

12) Remote control, supports MODBUS 



Specifications:  

1) Input voltage: 85 - 265V AC 50/60Hz

2) Power: <20W

3) EMC: Level A

4) EFT: Level 3 

5) Super-width LCD of 240 x 64 graphic lattice in blue backlight 

6) 10 filmy slight-touch buttons

7) 18 LED display indicators

8) Multi-communication ports of RS485, RS232 (RS485: <1200m, 

    RS232: <20m)

Features: 

1) TVR (three phase voltage protection relay) is a high-tech patent product, which

    is used for the large-scale digital integration

2) Testing wave form, amplitude and phase of voltage by PC to 

    judge whether anything wrong with it or not

3) The TVR is applied to the AC 50 / 60Hz and the rating voltage under 460V

4) It provides the relay protection for over voltage, under voltage, opposite phase,

    chopping phase and three phase voltage imbalance of electromotor input power

Features: 

1) It adopts advanced technology 

2) It is used together with controller series to measure the pressure of 

    central air-conditional's processors and other parts

3) Front thumbstall design, with shock-proof ability and stability 

4) It also has the ability of lightningproof, radio resistant and waterproof  

5) Small volume but high sensitivity and stability

3PH-204 is a terminal interface between user and units. It usually installs 

indoors to order on/off for air-condition terminal and set parameters; It can 

set activate control to host unit through 3PH-800 (the mate-product of 3PH 

series), it can cooperate with even 99 hand-operators. This series product 

is innovation in current control mode for atmosphere; each control not only 

has eight section and ice-water electric valve, but also can control adding / 

dropping humiditor and ventilator. It can be equipped to inspect thickness 

of CO2.
