Product Content Description:

Specification:
1. Product feature
1) Faceplate indicating lamps, indicating the situations of Load, Power supply, Over temperature alarm and Fuse break.
2) Soft starting time:5s. Soft stop time:5s.
3) Stable linear output.

2. Installation
1) SCR power regulator will produce internal heat during operation. Please install it vertically and leave some space for both sides to avoid rapid aging and damage of power module caused by bad heating off.
Humidity<=90%, ambient temperature:0~+40C.
2) Rated Capacity %

3) Main circuit wiring: NFB=MC=SCR(SCR power regulator)=Load
NFB can cut off the power to protect the equipment and personal safety during repair and maintenance.
MC can cut off power supply automatically to protect the equipment and avoid accidents when the power regulator fails.

3.Terminal wiring
30A~40A terminal wiring
1)Analog volt current input:
AC1/AC2: AC220V; +/-: Input; E3/E2: connected.
2)Analog volt current input with adjustable external VR:

3)Contact input:
AC1/AC2:AC220V; M/+: Switch; E3/E2/E1:VR10K
4) Manual input with adjustable external VR
AC1/AC2: AC220V; M/E3/E2:VR10K
5)Manual and Automatic input, M manual, A automatic:
AC1/AC2: AC220V M/E3/E2/E1: E3/E2 for VR10K and can switch to either A(E1) or M(M).
50A~400A Terminal
1) Analog volt current input:
AC1/AC2: AC220V; +/-: Input; E3/E2: connected; COM/NO: Alarm
2)Analog volt current input with adjustable external VR:
AC1/AC2:AC220V; +/-:Input; E3/E2/E1: VR10K; COM/NO:Alarm
3)Contact input:
AC1/AC2:AC220V; M/+: Switch; E3/E2/E1:VR10K; COM/NO: Alarm
4)Manual input with adjustable external VR
AC1/AC2: AC220V; M/E3/E2:VR10K; COM/NO:Alarm
5)Manual and Automatic input, M manual, A automatic:
AC1/AC2: AC220V M/E3/E2/E1: E3/E2 for VR10K and can switch to either A(E1) or M(M); COM/NO: Alarm
6)Multiple unit connecting is also available.

4. Input Signal
4~20mA, 0~20mA/1~5V,0~5V/ 0~10V, 2~10V

5. Types
TSCR-_a_-_b_-_c_-d
a represents Phase control, with 1 for single phase control and 4 for 3 and half phase control
b represents main power, 2 for 100~240V, 4 for 330-440V, 8 for 480V
c represents current load, for example, 80A, 100A, 200A, etc.
d represents phase shift control and the Code is P.
So, TSCR-4-4-050-P means a SCR means that it is 3 and half phase control and the voltage is 330-440VAC with a current load of 50A.

6.Current calculating formula:
Single phase: SCR ampere(A)=1.2*{load(kW)*1000/Voltage(V)}
3 phase: SCR ampere(A)=1.2*{load(kW)*1000/(line voltage(V)*1.732)}
