Control Techniques SP1404 The drive SP1404 is a universal variable speed AC Drive for induction and servo motors designed by the company Control Techniques. It is known as a uni-drive SP inverter that is manufactured to provide efficient and reliable motor control for various industrial applications by offering features such as easy installation, flexibility, and control options according to the requirements. Technical Specifications: The SP1404 supplies a nominal power rating of 3.0 kW or 5 hp for normal duty operations. It provides a maximum permissible continuous output current of 6.9 A when operating at switching frequencies from 2 kHz to 12 kHz. For a switching frequency of 16 kHz, the maximum continuous output current decreases to 5.9 A. For the drives heavy-duty cases, a nominal power rating of 2.2 kW or 3.0 hp is used. It delivers a maximum permissible continuous output current of 5.8 A for switching frequencies ranging from 3 to 8 kHz. This current is limited to 5.4 A for 12 Hz, declining to 4.3 A at 16 kHz. When operating under normal duty conditions at 40 degrees centigrade, the SP1404 exhibits fluctuating power loss across switching frequencies. At 3 kHz, the power loss is 102 W, increasing to 109 W at 4 kHz and 123 W at 6 kHz. The drive has an operating voltage range of 380 to 480V with a positive and negative tolerance of 10% and has an input control voltage of 24V DC, permitting the circuit to keep in on state even when the AC supply is disconnected. Operational and Installation Parameters: The SP1404 operates in ambient temperatures from 0°C to 50°C (32°F to 122°F), with output current by decreasing the rate needed above 40°C (104°F). When it is power-up, it requires a minimum temperature of -15°C (5°F), with a power cycle needed after warming to 0°C (32°F). Its cooling is maintained by forced convection procedure, and it can manage up to 95% non-condensing humidity at 40°C (104°F). The uni-drive SP series includes the necessary hardware to interface with nearly any feedback encoder type, allowing designers to choose the precise technology for their specific requirements. Safety Precautions: The drive is designed for professional integration into complete systems and equipment. However, wrong installation can create safety risks due to the high voltages and currents. Careful attention to electrical installation and system design is necessary to prevent hazards during normal operation or in case of equipment failure. Motor parameter values in the drive impact motor protection. So, the correct motor-rated current for proper thermal protection is required, and it is important to note that default settings are not worth relying upon. Frequently Asked Questions: Under normal conditions, what is the power loss of the SP1404 drive at frequency 3KHz? The drive SP1404 has a power loss of about 102 watts at the operating frequency of 3KHz. This value represents the energy dissipated during its operation, affecting overall efficiency. What value of DC input current is permissible when AC current is removed in SP1404? The drive operates at a control input current value of 24V DC to keep the drive in an operational state. This ensures that the drive remains functional even when the AC current is absent. How much is the nominal power rating at standard conditions for SP1404? The drive has a nominal power of 3 kilowatts or 5 horsepower for accurate operation under normal duty conditions. This rating indicates the maximum continuous power the drive can handle effectively.
