Product Description:
The Danfoss 175Z4138 Converter offers dependable performance through its continuous torque nominal power of 18.5 kilowatts. It is designed for general applications and is able to accommodate demanding conditions like overloads and surges in the rotational force.
The 175Z4138 frequency converter dissipates 250 watts of energy as heat when it is active. It can handle 22 kilowatts at a short term peak and its capacity reduces to 18.5 kilowatts under continuous torque at 160 percent. Its shaft has an output power of 30 horsepower which means the connected motor can provide this much mechanical rotation when powered by this module. It does not feature built in radio frequency interference suppression which means electrical noise might be present on power lines. It is designed to be powered from a 3 phase grid with voltages ranging between 380 and 500 volts. Its current and voltage transformers associated with it can function up to 60 Hz. Its power capability is 36.6 kVA when it is delivering power at 240 V. It does not feature or allow an additional interface for fieldbus networks. It consumes 88 amperes from the supply under normal operation and it is featured with a local control panel.
The 175Z4138 frequency converter or its filtering parts has an inductance of 0.083 mH that helps smooth current flow and mitigate high frequency disturbances. It delivers 73 amperes of standard current to the motor when it is operating at two hundred volts. It efficiently transmits energy from the input to the motor side as only 1.7% of reduction occurs in the voltage when electricity passes through the converters.
Frequently Asked Questions about 175Z4138:
Q: How does the Danfoss 175Z4138 converter handle temporary overloads?
A: It can deliver higher torque for short durations without damaging components, allowing motors to start heavy loads smoothly. This makes it effective in applications like conveyors or compressors.
Q: Why is power dissipation in a converter important for system design?
A: Heat loss requires proper ventilation or cooling to prevent overheating. Without it, lifespan and efficiency of the drive and nearby equipment can be reduced.
Q: How does voltage drop in a frequency converter impact motor performance?
A: Even a small drop reduces the effective voltage applied to the motor, slightly lowering torque. In most cases, this is negligible but must be considered in precision systems.
Q: What benefit does the compact IP54 enclosure provide?
A: It shields against dust and splashing water, extending reliability in industrial areas. This protection allows installation in workshops or production floors without special housings.
Q: Can the 175Z4138 be integrated with automation networks directly?
A: No, it lacks options for fieldbus cards, so integration requires external gateways. This limits direct communication but doesn’t prevent use in standalone motor control setups.
