Connection diagram

• It is recommended that you connect as shown in the picture.

• Fuse is not installed inside the product.

• For Fast acting fuse, select the fuse that matches the current/voltage used.
  Ex) Actual operating current 25A: Bustmann’s 35ET (using fuse over 25 A r.m.s) [35 A → 50FE (35 A r.m.s or more), 50 A → 71FE (50 A r.m.s or more), 70 A → 100FE (70 A r.m.s or more)]

• High current flows, so use the compression terminal to tighten the connections.

control input.
It lights on longer if the output amount is large and it is continuously ON if it outputs 100 % continuously
SOFT| To use the “Soft start, Soft up/down” function, turn Soft VR clockwise, and the LED will turn ON
O.C| After overcurrent occurs, LED ON when current exceeds O.C VR set value for the protection of product and load
S.S| If the SCR is shorted, the power is still on even though there is no control input, and the heater continues to overheat. Therefore, if the current flows over 5 A without the control input, the LED turns ON and alarm.

※ Alarm terminal operates as A contact (N.O).

Function description

Phase control

• Phase control is to control the AC power supply applied to the load proportionally according to the control input signal as changing phase angle (0 ~ 80 degrees) in each half cycle, 8.33 ms.

ON/OFF control (25 A, 35 A Only)

• If ON/OFF contact is ON, then the output is 100 %. ON/OFF always operates near zero point.

※ Even though the control input signal is ON, the output is 100 % when ON/OFF control is used.

Fixed cycle control (optional)

• The output is set at a fixed period (Approx. 1.6s) and the ON / OFF control is repeatedly controlled at a constant rate according to the control input.

Variable cycle control (optional)

• It is a method to control by using the number of cycles of the AC Sine waveform, not by controlling the cycle.

VR Description

SOFT START

• It is a function to protect the load from a load with a large start-up current (inrush current), and gradually raises the output.

※ Setting time: 0 ~ 60 sec (0 sec setting at shipment)
※ If SOFT START VOLUME is turned to a minimum, SOFT will not operate.

Output Voltage Limit (PW MAX)

• This function is to limit the output separately from the control input. When the control input is 100%, changing the POWER VR to the left will reduce the output. (100% setting at shipment)

Overcurrent setting (O.C) (50 A/ 70 A Only)

• Function to protect power regulator (TPR) and load when over current occurs. (Phase control only)

※ Setting range: 0 ~ 84 A
※ Default: Set to 84 A at shipping
※ The maximum value of the overcurrent detection value is set to 84 A when the variable resistor is on the right side.

Installation

1. Install in the vertical direction as shown above. Please use only 50% of the rated current when installing the product horizontally or horizontally in unavoidable circumstances.
2. When installing several products closely, please install at intervals of 5cm width and 10cm height as shown below.
3. Install the wiring duct so that it is not more than half the height of the heat sink so as not to block the flow of air.
4. Please pay attention to airflow. The lower the ambient temperature, the better the durability and reliability of the product and the longer the life. Use caution temperature is 0 ~ 40 ℃.
5. When wiring, use a crimp terminal to tighten the terminal part where high current flows. If the joint surface is poor, wiring and terminals may overheat and lead to a fire.
6. To prevent electric shock, this product requires a third or more grounding before turning on the power. Since there is no separate ground terminal, it is recommended to  install the bracket together with the ground terminal when installing the panel
