ALMEGA
The MP2G or ALMEGA has proved to be the right combination for new and refurbished installations
The combination of using our MP2G or ALMEGA processor with the Magnetek HPV® 900 II drive has worked well on many installations, using serial coms communication (ALMEGA only) between the drive and our processor. The processor also connects directly to our serial indicator and speech module, providing full programmability of up to 48 floors. The direct serial communication to motor drives (VVVF) provides better reliability and control, and a wealth of information can be accessed from the drive for diagnosis/monitoring purposes. Windows application software is available to allow the user to change parameters and settings to suit the lift installation. The software also provides the user with diagnostic tools for viewing detailed information regarding the status of the lift and motor drive.
The MP2G or ALMEGA are not supplied on new controllers, but are readily available as replacement parts.

The HPV900 Series II AC Elevator Drive
The new range of Series II AC Drives are available to the elevator market for use with either MP2G or ALMEGA controllers. They are designed for both new installations and modernisation projects, and provide advanced closed-loop vector control for superior performance. The HPV900 II offers the fastest, easiest set-up adjustment, fewest call backs and the lowest total lifetime cost. This cost-effective AC drive gives you accurate acceleration and deceleration, resulting in a smooth ride quality for high and moderate-speed applications. Magnetek’s proven technical expertise, plus our superior customer service, has placed us as the world’s leading source of innovative, built-to-last elevator drives.

ALMEGA & ALMEGA II - Now Even Greener
In response to the ever growing demand for energy efficiency, Lester Controls have developed a range of eco-friendly features designed to integrate with our highly successful ALMEGA series controllers and now our latest range – ALMEGA II.
For modernisation projects where existing DC geared and gearless machines are to be re-used, our DC-Quattro DC control system solution, utilising a Magnetek DC-PWM regenerative drive, provides typical energy savings of over 30% against DC-SCR drives. Against Motor Generator (MG) sets, savings rise to 45%. Additional benefits of this high-tech solution are reduced mains harmonics and power factor improvement.
Our ongoing energy-reduction techniques provide:
- Higher standby power savings
- Higher drive running power savings
Standby Power: How we achieve these savings:
- Car illumination – auto shutdown of car lights when the lift is inactive
- Indicators – auto reduction of indicator intensity output (adjustable) when the lift is inactive
- Fans – automatic power reduction through Drive/Motor/Car Fan switch-off when the lift is inactive
- Permanent Magnet Gearless machines – having zero standby losses compared to DC machines
Running Power: How we achieve these savings:
- Floor-to-floor times are minimised using Lester Controls’ Direct-to-Floor (DTF) system, with running cost savings and improved ride quality performance associated with DTF profiling
- Closed-loop control provides improved speed tracking, further reducing peak current demands and optimising power factor efficiency
- Using Magnetek’s ‘Quattro’ DC and AC fully regenerative drive ranges, power is diverted to the mains supply, eliminating wasteful energy otherwise diverted through dynamic braking resistors
