This module stands as a reliable solution that combines electrical performance, safety standards and operational adaptability for continuous operation.
This 175H7266 variable speed drive includes a filter that supports compliance with electromagnetic standards and it allows flexible speed control as its output frequency reaches up to 500 hertz. It has 10 amperes of peak input current that shows its power consumption in a balanced way. Its cable supports safe electrical connection due to its maximum cross section of 2.5 millimeters squared. It is highly protective to operate in high load conditions as it accommodates maximum pre fuses of 25 amperes. Its supply voltage of three phases 380/400/415 volts supports regional power standards. It is highly adaptable to global power networks as its supply frequency is 50/60 Hertz. Its 0.96 efficiency at 100 percent load ensures effective conversion of energy. It allows switching on input 2 times per minute and its vibration test level of 0.7 grams make sure stable mechanical integrity.
The 175H7266 drive rated power of 4 kilowatts ensures stable performance in different industrial automation fields. It is highly protective from dust particles and splashes of water as it carries an ingress protection 54 class. Its input phase is 3 that aligns with standard three phase industrial automation systems. Its technical design aligns with requirements of power control applications that demand precision, efficiency and operational security. In this module each of its specifications works in balance to offer reliable and consistent operation.
Frequently Asked Questions about 175H7266:
Q: How does the built-in filter affect installation of the 175H7266 drive?
A: The built-in filter reduces electromagnetic interference so additional external filters are often unnecessary. This simplifies wiring layouts and saves cabinet space.
Q: What is the practical impact of a 500 Hz maximum frequency?
A: It allows motors to operate at higher speeds than standard drives. This is useful in applications requiring extended speed ranges like spindles or specialized pumps.
Q: How does efficiency of 0.96 at full load affect system performance?
A: High efficiency reduces heat losses and lowers energy costs. It also minimizes the cooling demand on enclosures and extends component lifespan.
Q: Why does the 175H7266 specify switching only two times per minute?
A: Limiting switching prevents stress on internal components and input relays. Exceeding this rate can cause premature wear or potential trip faults.
Q: What are the implications of a 10 A input current rating?
A: The drive requires conductors and breakers sized appropriately for this current. It also indicates the typical power draw under full operation.
