Industrial Electrical & Motor Control Solutions
Variable speed drives, soft starters, circuit protection and control devices for pumps, HVAC systems, industrial machinery, infrastructure and building-services projects in Singapore.
Application First
Drives, Motor Starting, Circuit Protection & Control Solutions
The right electrical solution starts with the application. A pump, AHU fan, conveyor or fire pump may use similar motor ratings, but the correct VSD, soft starter, circuit breaker, contactor and protection strategy can differ significantly depending on the operating duty and system requirements.
Trans-Digi supports panel builders, M&E contractors, consultants and project teams with variable speed drives, soft starters, MCCBs, MCBs, RCCBs, contactors, overload relays and control devices, together with product selection and technical support.
Where required, we also provide parameter configuration, testing and commissioning to support correct installation and operation before project handover.
- Products selected for the motor duty and application
- VSD and soft starter parameter configuration
- Circuit protection and motor-control requirements considered upfront
- Drives, starters, protection and control products available within one portfolio
Application 01
Pump & Water System Solutions
Variable speed drives and motor-control equipment are widely used in booster pumps, transfer pumps, pressurisation systems and water-pumping applications where pressure or flow must respond to changing demand.
Depending on the system design, the solution may include VSDs for variable-speed operation together with MCCBs, contactors, overload protection and control devices for the associated motor circuits. Multi-pump systems can also make use of PID control, alternation, cascade operation and sleep/wake functions.
- Closed-loop PID pressure or flow control
- Multi-pump cascade and alternation
- Sleep and wake operation during low demand
- Dry-run and pump protection functions
- Controlled acceleration and deceleration
- Circuit protection and motor-control components for pump panels
Application 02
HVAC & Air-Handling Solutions
HVAC systems use variable speed drives to control air-handling units, ventilation fans, exhaust fans and other motor-driven building-services equipment according to changing demand.
In addition to the VSD, the complete motor-control circuit may include MCCBs, contactors, overload protection and control devices, while communication options such as BACnet or Modbus can support integration with building management systems.
- Variable-speed control for AHUs and ventilation fans
- BACnet and Modbus communication options
- BMS and control-system integration
- Configurable interlocks and operating modes
- Motor status, speed and fault monitoring
- Protection and switching equipment for HVAC motor circuits
Application 03
Chilled-Water & Cooling System Solutions
Chilled-water plants require coordinated motor control across primary and secondary chilled-water pumps, condenser-water pumps and cooling-tower fans.
Variable speed drives allow motor speed to respond to plant demand, while soft starters may be suitable for selected fixed-speed duties. The associated electrical system can also require MCCBs, contactors, overload protection and control devices sized to suit each motor and operating duty.
- Primary and secondary chilled-water pump control
- Condenser-water pump control
- Cooling-tower fan speed control
- Differential-pressure and temperature-control applications
- Soft starting for suitable fixed-speed motors
- Circuit protection and motor-control coordination
- Integration with plant controls and BMS systems
Application 04
Industrial Machinery & Motor Control Solutions
Industrial machinery such as conveyors, mixers, agitators, compressors and process equipment can require variable-speed control, controlled motor starting and coordinated electrical protection.
Product selection depends on motor load, starting torque, duty cycle, acceleration requirements and overload characteristics. Depending on the application, the solution may combine VSDs or soft starters with MCCBs, contactors, overload relays and control devices.
- Variable-speed control for industrial machinery
- Controlled motor starting with soft starters
- Constant-torque and variable-torque applications
- Multi-speed and programmable control functions
- Overload and motor protection
- Contactor and control-device coordination
- Braking and accessory options for suitable applications
Application 05
Infrastructure & Public-Sector Solutions
Infrastructure and public-sector projects often require electrical equipment to meet defined technical specifications, documentation requirements and project delivery schedules.
Trans-Digi supplies VSDs, soft starters, circuit protection and motor-control products for transport, infrastructure and public-sector applications in Singapore, with technical documentation, product selection, testing and commissioning support available where required.
- VSDs and soft starters for infrastructure applications
- MCCBs, MCBs and related circuit protection
- Contactors, overload relays and control devices
- Product selection against project specifications
- Datasheets and technical documentation
- Testing and commissioning support
- Project references across rail, public-sector and infrastructure applications
Application 06
HDB & Residential Building Solutions
Public and private residential developments use electrical control equipment across booster pumps, carpark ventilation systems, distribution boards and other building-services applications.
Trans-Digi supports residential projects with VSDs, soft starters, MCCBs, MCBs, RCCBs, contactors and control devices, together with product selection, parameter configuration, testing and commissioning for both new installations and replacement works.
- Booster and water-pump VSD applications
- Carpark ventilation fan control
- Multi-pump sequencing and alternation
- MCCB, MCB and RCCB circuit protection
- Contactors and overload protection for motor circuits
- VSD replacement and upgrading projects
- Testing and commissioning support
