For proper and safe operation in Controlled-Current mode, you must obverve the following guidelines: 1. Properly attach a load before operating the amplifier. Use only the Output and Sampled Common terminals. DO NOT use the Common terminal. 2. DO NOT use a blocking capacitor. The load must have a DC path. 3. Never leave the load open. If you feel the load must be fused, which could lead to a poten- tial open circuit, please contact AE Techron Application Engineering department. ... -
