LTU Amplifiers

The LTU Amplifiers are a series of highly reliable servo amplifier products by Bosch Rexroth Indramat. They are specifically designed to be operated with the SB356 System Box, BT356 Card Rack, and either the SE352 or SE352M Control unit, providing control for up to two LTU amplifiers mainly used in conjunction with ErgoSpin handheld nutrunners. The amplifiers run maintenance-free for designated purposes and house a graphic LC display for prompt error code depiction and result metric display like torque, angle, gradient, and time. The intermediate circuit in each amplifier is safeguarded by two security fuses to ensure operational safety. If these fuses blow, the operation of the amplifier becomes impossible.
