H100 Frequency Converters for Fans and Pumps

H100 Frequency Converters for Fans and Pumps.

H100 HVAC series frequency converters for fans and pumps.

Main Advantages:

- Control of multiple pumps (up to 5)
- Energy savings counter
- HVAC keypad
- Advanced protection functions for pumps and hydraulic systems
- Stable system control

Multi Motor Control (multiple-motor control)

MMC is used when a single frequency converter controls multiple motors in pumping systems. It can manage 1 main motor and 5 auxiliary motors.

Energy Saving Counter

Commercial energy consumption is compared with the energy used by the drive to calculate the amount of energy saved.

RTC (Real Time Clock) Module and Scheduling

The operating schedule can be set so that, during specific periods, it meets user or system requirements. The RTC (real-time clock) ensures selected functions operate only during the set times.

Soft Start and Stop Function for Pumps

Prevents pump damage caused by sudden pressure changes during startup and shutdown.

Flow Compensation

Compensates for hydraulic losses that occur when pipe runs are long by adding a compensation level depending on the converter’s output frequency.

Overload Protection

When using pumps—including no-flow and dry-running pumps—below the set frequency, the drive triggers a warning when a fault occurs; via parameters you can select Free-Run or Stop.

Pump Cleaning Function

After pump operation, efficiency may decrease when foreign substances get stuck in the rotor. The “Pump Clean” function removes debris to extend pump life and reduce potential losses.

Pipe Break Detection

After PID operation, pipe damage or leakage is detected, showing a warning or fault.

Fire Mode

In emergencies, such as a fire in exhaust fans, provided the hardware has not failed or encountered a critical fault, the drive continues to run continuously at the set frequency and direction to protect other systems.

Lubrication Control

When a control command is executed in flow/oil systems, lubrication signals are sent for a set period before starting the motors. Drive control starts immediately from the signal output point until the signals turn off after the set time.

Preheating

Preheats motors for a specified time to prevent condensation.

Control

If an expansion vessel is installed in the system, the frequency converter commands the vessel to open/close or receives feedback signals for protection.

KEB, Kinetic Energy Buffering

When KEB is enabled, in the event of a loss or momentary interruption of input voltage, the drive maintains DC voltage using the motor’s regenerative energy.

Communication Module

- Built-in RS-485 communication, Modbus-RTU, Metasys N2, and BACnet MS/TP
- Optional LonWorks module

HVAC Application Keypad

Used to issue commands, configure drive parameters, and monitor drive status.
- Choose HAND (Local Control Mode) or AUTO Mode (Remote Control Mode)
- HAND Mode: used to select frequencies or issue run/stop commands
- AUTO Mode: the drive operates via the keypad, multifunction terminal block, and communication
- Fault status monitoring

DC Reactor (DC Choke)

A built-in DC choke effectively improves power factor and reduces THD (total harmonic distortion). The DC choke is standard on H100 frequency converters rated 37–500 kW (400 V).

Built-in EMC Filter

- Versions 0.75–30 kW (400 V) and 110–500 kW (400 V) include a built-in (C3) EMC filter
- Optional (C3) EMC filter for versions 37–55 kW (400 V)
- Versions 75–90 kW meet EMC specifications even without a filter.
