The VS3-015-4-UL1-0 from Johnson Controls functions as a variable speed drive suitable for various industrial uses. Its frame size is designated as Frame 2, giving it a balanced design for handling dynamic loads. This drive weighs 23 lbs and delivers an output of 15 horsepower.
In terms of electrical specifications, the device operates at a primary voltage of 480 volts AC, with a versatile input range that allows for fluctuations from 380 to 600 volts, adjusting within a -15% to +10% margin. It can function across input frequencies of 50 to 60 Hertz, accommodating variations that extend from 45 to 66 Hertz.
Protection is provided with an NEMA Type 1/IP21 rating, ensuring it is safeguarded against dust and light moisture intrusion. The drive has an operational temperature spread from -10°C to 50°C, with a maximum of 60°C permitted under constant torque conditions and some derating applied. Its storage temperature parameters are considerably broader, ranging from -40°C to 70°C.
For safety features, the VS3-015-4-UL1-0 has a short-circuit withstand rating of 100 kAIC, mitigating risks in sudden fault situations, and a lower rating of 5 kAIC with regards to systems lacking fuses or breakers. Communication capabilities are robust, incorporating BACnet/IP, MS/TP, Modbus TCP, RTU protocols, and the proprietary Johnson Controls SA Bus.
This drive's performance in overload scenarios includes a 110% continuous rating for 10 minutes, peaking at an initial rating of 200% for just 20 seconds. The switching frequency can adjust between 1 and 12 kHz, with a default setting of 4 kHz, accommodating diverse motor control applications.
