Product Description:

The LT303 is a slim and compact servo controller built to be used in sophisticated control and processing systems. The amplifier is designed by Bosch Rexroth Indramat, it comes with rust-resistant aluminum housing, and it is characterized by a long-lasting, maintenance-free industrial operation. This controller is an internationally certified product that has been tested to meet the safety standards and operation requirements of the United States and the European Union. It is delivered in a recyclable cardboard box that carries the type label containing important identification and certification information. The operating input current of this controller is 3.5 amperes; it can also operate with an input voltage supply of about 350 volts. This product functions at a top level with very little risk of overheating, and the low heat produced by the motor efficiently dissipates from its housing through the natural process of convection and thermal radiation.

The LT303 servo controller is designed with a single connection interface, which is present on its front panel; there are also special LEDs on this front panel that operators can use to monitor the connection status at the integrated interface in real-time. The LT303 is an extremely quiet product; despite its high operation efficiency, it maintains an impressively quiet operation. Also, multiple units of this product can be installed side by side without any significant effect on its performance standard.

The LT303 servo controller belongs to the 3K3 product category, and it is intended to be used at a relative humidity level that is not higher than 90 per cent. Water condensation around the controller during its operation should be avoided. Wake Industrial provides this product with a 12-month warranty, which covers unexpected machine failure.
