Product Description
Soft start time is adjustable for 20s (time rise refers to soft start voltage set to 380V);
The starting voltage is 150-250V, which can be adjusted to a rated voltage of 380V.
There are three ways to use the product:
When the switch of the module control end is closed, the main power supply gets power and the soft start starts.
(2) When the main circuit is powered on, it is controlled by the module control end contacts, and the closure starts with soft start;
(3) The main circuit is powered on and controlled by the module control end contacts. With 5-24Vdc signal input, the soft start starts.
The three-phase soft-start module contains the following procedures:
(1) lack of phase protection function;
(2) Overheat protection function;
(3) Soft start function;
(4) Soft stop function (soft stop to 0 or soft stop to soft start value or off);
Phase sequence protection function (can be set on or off);
(4) Both functions can be switched off or on at will.
1. Soft start, soft stop (to start value or 0), sequential protection
2. Soft start,
Soft stop (to start value or 0), out of phase protection
3. Soft start, no soft stop, ordered protection
4. Soft start, no soft stop, out of phase protection
There are 6 states in the module, which are flexible and powerful.
The initial state is: soft start, no soft stop, out of phase protection.
If you need to set it to another state, you can consult customer service or refer to the instructions.
Example: If the module state is set to soft stop to 0, there is sequential protection and the two potentiometers are twisted to the corresponding positions of 150V and 20s, respectively.
At this time, the main circuit is powered on, the control switch is closed (or 5-24Vdc), and the output voltage of the module will gradually increase from 150 V to 380 V for 20 seconds.
If the control switch is disconnected (or 5-24Vdc is disconnected), the module output voltage will slowly decrease from 380V to 0V for 20s.
(If the soft stop setting is to stop to soft start value, the module output voltage will slowly decrease from 380V to 150V for 20s and then turn off immediately).
