A variable frequency drive is an electronic device that allows you to start, stop, and control the speed of a three phase motor. It is also a motor starter as it is equipped with overload protection. Read more »
What is the difference between a 'new surplus' motor and a 'factory new' motor?
Our New Surplus electric motors and drives are new and unused overstock or discontinued items offered at lower prices and come with our 90-day warranty.
Factory New products are competitively priced and come with a manufacturers warranty.
Variable frequency drives (VFDs or inverters) now play an important part in major industry.
Within the last 10 years they have been perfected to control and vary the speed of 3 phase electric motors. They serve many purposes, besides speed control. Homeowners and hobbyist alike, who have lathes or milling machines with a 3 phase motor, usually don't have 3 phase power to operate. These VFDs (instead of using a rotary phase converter) can now be used to convert single phase power to 3 phase power. Read more »

Specialized Functions for Fan and Pump
The iP5A, specifically designed for HVAC application, provides stable and cost-effective system performance.
PID Control -
In the centrifugal fan and pump field, PID control is provided as a standard function in order to maintain a constant control of pressure, flow and oil level. This function includes Pre-PID, Sleep and Wake up and output inverse subfunctions.
Dual PID -
Where external or cascaded PID control is required, the built-in dual PID algorithm of the iP5A can be utilized to satisfy various system requirements
Multi Motor Control (0.75-450kW ratings only) -
The iP5A MMC function provides cost-effective, simultaneous control of up to eight motors, without requiring external controllers.
Energy Saving and High Efficiency
The iP5A, specifically designed for fan and pump applications, guarantees energy savings by optimizing the system.
Sleep and Wake-up Function -
Energy savings are obtained through the Sleep and Wake-Up functions of the iP5A, which enable the drive to automatically switch off during user-programmed low-load conditions and then to start up again when process demand increases.
Pre Heating Function -
When using the inverter in damp conditions, this function protects both the motor and the inverter's output
Flying Start Function
When 2 or more fans, or a high inertia load are connected to the inverter, the iP5A detects the motor speed after a momentary power failure, enabling the motors to be smoothly reaccelerated without mechanical and electrical shockloading to the system.
Automatic Energy Saving -
Load change may incur energy losses but the optimized flux control of iP5A results in more outstanding energy saving
compared to previous models.
Intelligent Control
Because of effectual functions and protection algorithms, the iP5A provides constant performance,
in spite of external power fluctuations.
Constant and Stable Performance -
In spite of external voltage fluctuations and lightning surges, the iP5A optimizes motor performance.
Improved System Management during Power Dips and Momentary Power Outages -
During Power Dips or Momentary Power Outage, the inverter output can be maintained by utilizing the residual
mechanical energy in the load as a regenerative source. The duration of the power-dip ride-through depends on the load
characteristics.
Safety Stop -
During unexpected power failure conditions, the iP5A can bring the load to a controlled stop, by utilizing the inertial energy. This can prevent further process problems or accidents.
Current Leakage Reduction Algorithm -
Under damp conditions, leakage currents can occur when using inverters. These currents can cause a system failure. The iP5A low-leakage PWM algorithm reduces these leakage currents to ensure reliability of operation.
Flux Braking Algorithm -
This algorithm reduces deceleration time, thereby improving system efficiency
Automatic Carrier Frequency Change -
By taking ambient temperature into account, the iP5A can automatically adjust the Carrier (Modulation) Frequency.
Protection -
The iP5A has optimized protective functions, such as safety stop and pre-excitation of the motor, amongst others.
User-friendly Interface and Easy Maintenance
The iP5A construction allows for easy maintenance, with ease-of-access to all components.
NPN/PNP Input -
iP5A has both NPN and PNP input, and you can select one of them easily.
Abundant I/O Suggestion -
8 Digital Inputs / 4 Digital Outputs / 2 Analog Inputs / 4 Analog Outputs / 1 Pulse Input / 1 NTC/PTC Input
Various Units of I/O Display
The iP5A display can be calibrated in many different types of process units.
Built-in RS485 and Optional Communication -
The built-In RS485 allows for communication without external option. However, the optional communication boards enable the iP5A to talk to BMS and most Industrial Systems
Long-life Condenser and Simple Framework -
iP5A adopts long-life condenser and enables easy maintenance in simple framework.
Consumption Time Display -
iP5A displays consumption time of components so that users can replace them in time.
Others -
Removable terminal board
External fan available
Cooling fan on/off control
