A dynamically developing industrial equipment manufacturing company has once again released another successful industrial electronics product. This time it's the SS70 soft starter. The product is very powerful and functional. There are many different "interesting features" that are rarely found in many similar products, but here it's a real treasure trove. Let's describe what's interesting about this product.
At first glance, this soft starter reminds us of a certain well-known brand, but this is a coincidence.
The current matches the declared power, which is very important when selecting equipment.
Built-in bypass. That is, the bypass starter is built into the device body.
This device performs not only the soft start function but also soft stop. This is very good for many applications, for example, pumps (reducing water hammer) and other mechanisms (extending equipment life).
The line includes devices for operation with voltages of 400V, 460V, and 660V.
Control board voltage 220V!!!
Various start methods:
- Current limiting
- Current ramp
- Voltage ramp
7. Protection functions: phase loss, over/under voltage, overcurrent, phase current imbalance, etc. Comprehensive motor protection.
8. Acceleration and stop time can be set from 1-120s!!! Usually, even with very well-known manufacturers, the maximum acceleration/braking time is 60s.
9. RS-485 interface availability. Not every manufacturer can boast of this.
10. 3 Digital inputs – 1 of which is freely programmable.
11. 2 Relay outputs, 1 for start failure, and the other freely programmable.
12. Analog output – 4-20 mA or 0-10V
13. Ability to connect an external RT100 thermistor.
14. Configurable protection parameter limits.
15. Fire Mode – the device operates despite failures.
16. Operating temperature -10℃～+40℃. Not every soft starter can boast such an operating temperature range. Usually above 0.
17. Very wide power range 5.5kW - 630kW (11A - 1260A
18. Start delay function up to 60s.
19. No switches like many manufacturers use. Parameters are entered via a control panel.
20. Start current limit up to 600% of nominal.
These are the main interesting features collected in this soft starter. Thus, it is suitable for many applications, from simple mechanisms (pumps, fans) to very complex ones such as mills, centrifuges, etc.
Currently, frequency converters are usually used to operate motors, but it is not always necessary to regulate speed, but merely to start the motor. Starting with a contactor is also not optimal, as it significantly loads the network + minimal protection is also required. However, in many cases, a star/delta start and thermal protection equipment will cost more than an SS70 soft starter with a bunch of motor protections.
