CTI Load transfer control panels
Presentation
The FG Wilson Load Transfer Panel range offers an electronically controlled response to power outages. With flexible, upgradeable options and a high level of functionality FG Wilson transfer panels provide 24-hour automatic control of standby generator sets, 365 days a year.Benefits
- Fully automatic mains failure sensing and generator set start signal
- Pre-programmed enabling the panel to run on installation with the ability to customise if necessary
- Fast acting switches reduce transfer times between set and utility power
- Available from 63 – 160A
- Seamless integration with FG Wilson digital control panels
Features
- Automatic and manual operation
- Automatically provides generator set start signal upon detection of mains failure, overvoltage or loss of phase
- Automatic mains re-transfer function
- Flexible, upgradeable options
- Test operations and sequences accessible from panel or remotely
- Manual switch operation possible via external handle
- LED functions display showing generator set / mains availability and switch position
- LCD display for voltage and timers
- Load transfer panel range meets ATS IEC 60947-6-1 standard
Main features
Set routine times for delay on starts, delay on transfer, delay on re-transfer and run on timer
Allows on/off load tests at routine service checks.
For straightforward programming and testing. Password protection is included.
Switch can be padlocked in all three positions for added security and safety. Only possible in manual operation mode.
Fully integrated handle for manual operation.
Auxiliary/volt free contacts for remotely monitoring the switch position.
Generator set remote start signal and terminals for remotely monitoring the system.
Auxiliary inputs for automatic control, remote test on load and manual re-transfer.
For added protection.
Panel can be wall mounted for greater flexibility in positioning.
Allows for pole voltage sensing.
Shows status of utility power, generator set and switch at all times
Shows detailed status of system at all times for greater awareness and control.
Allows the connection of neutral cables from utility power, generator set and load without having the neutral broken by the switch during transfer operations.
