About SVX025A1-4A1B1

The SVX025A1-4A1B1 SVX 9000 Adjustable Frequency Drive by Eaton Cutler-Hammer is an open 25HP variable frequency drive, with a NEMA Type 1 enclosure and an Internal Brake Chopper Circuit option, used for the speed control of industrial motor applications. The drive, like every SVX 9000 drive, has a standard NEMA Type 12 Alpha-Numeric keypad which allows for local and remote operation, and it has a Built-in Quick Start Wizard in its programming, for smooth start-up. The SVX025A1-4A1B1’s operational voltage range is 380V AC to 500V AC, with a +10% to -15% voltage tolerance at 50/60Hz, and with a 25HP drive’s power rating with 100 KAIC short-circuit rating. It has an output voltage range from 0 to the rated input, with a programmable output frequency range of 0 to 320Hz, and it provides overload current capacity of 110% for 1 minute. The SVX025A1-4A1B1 has an output over current capacity of up to 250% of the rated input rating, with a 0.01Hz signal resolution, and it provides motor control via the Sensorless Vector Control which is suitable for open loop application.

It has an adjustable carrier frequency range of 1 to 16 kHz (10 kHz default), and it provides 30% x Tn DC brake torque with its Internal Brake Chopper Circuit option. The SVX025A1-4A1B1 has 2 programmable 0 to 10V DC/4 to 20mA 10-bit Analog inputs with an accuracy within ± 1% V/Hz, and with 200kΩ and 250Ω input impedance, and it also has 6 programmable 18 to 30V DC (+/-) digital input. The drive has a 10-bit, 0 to 20mA Analog output with a 500Ω maximum output load, and ±2% output accuracy, and it also has a 50mA/48V Digital Open collector output, with 2 programmable Form C relay outputs. The drive offers motor overload protection, under/over voltage protection, and motor stall protection. It has a functional temperature range of 14ºF to 122ºF, at 0 to 95% non-condensing humidity, and it is stored at –40ºF to 158ºF temperature range. The drive is built to function optimally at a maximum altitude of 1000m (3300ft) without de-rating, and it is built to resist an operational 15G shock, with 1G vibration at 5 to 50Hz. The SVX025A1-4A1B1 weighs approximately 5Kg (11lb), and it has total dimensions of 327mm x 292mm x 190mm (12.9in x 11.5in x 7.5in).
