Get real energy savings with regenerative power supplies

How can we cut the cost of energy bills in the hoist and crane sector? Gefran’s regenerative power modules can cut costs significantly and produce clean energy.

Discover Gefran's many solutions for all industrial lifting systems.

Lower the electricity bill?

Companies incur enormous costs for electricity, which accounts for a large portion of their total annual costs. They are considered one the principal factors obstructing industrial growth and economic recovery.

How can you save energy in the Hoist and Crane sector?

Gefran’s energy-saving proposal

Our regenerative power supplies satisfy the most demanding work cycle requirements of industrial hoist systems.

Regenerative power supplies exploit inertia loads to save a great deal of energy and let you significantly improve your systems.

AFE200 regenerative power supplies

AFE200 regenerative power supplies are designed to work on networks from 400VAC to 690VAC in a power range from 22kW to 1.6MW in heavy duty, and to power the DC bus of ADV200-DC inverters.

In addition to highly dynamic 4-quadrant control, the AFE200 power supplies generate clean energy, i.e., at cosφ=1 with extremely low harmonic distortion (THDi ≤ 3%), for real energy savings.

SMB200 unidirectional and FFE200 regenerative power supplies

The SMB200 is a unidirectional AC/DC power supply designed specifically for creating common DC bus systems. It is designed for networks from 400VAC to 690VAV in a current range from 750ADC to 5800ADC in heavy duty.

On the other hand, when regenerated energy is 30-60% of driven energy, SMB200 unidirectional and FFE200 regenerative power supplies can be linked in parallel to power the common DC bus.

The FFE200 series permits bi-directional energy flow from a common DC bus and is designed for networks from 400VAC to 690VAV in a current range from 550ADC to 4000ADC in heavy duty.

SMB200 power supplies are sized for the entire driving power; the FFE200s only for regenerated power.

Although with lower performance in terms of THDi compared to AFE technology, this combination (appropriately sized) provides significantly lower system costs.
