The internal current loop is presented in the Figure 4. When a parameter of the CSA96 is modified, the new parameter value is automatically saved in a non-volatile memory. The parameters of the CSA96 are automatically recalled on startup, so that the user does not have to reconfigure the board on every power-up. -

Danger 7.7.3.EMC considerations It is highly recommended to use shielded cable to connect the actuator to the CSA96 and for the Control Port connection. Keep all wires and cables as short as possible. CEDRAT TECHNOLOGIES Current Switching Amplifier... -
Page 20: Theory Of Operation
CURRENT SWITCHING AMPLIFIER 8. THEORY OF OPERATION 8.1. PRINCIPLE The switching electronic CSA96 is dedicated to supply and control magnetic actuators. The CSA96 includes a power supply with a maximal power given in the technical data sheet. Actuator Figure 12 – Output stage principle. -
Page 21: Limitations And Protections
Example: A CSA96 providing 20A at 200Vpp with a sinus waveform (1kVA) to an ideal inductor consumes less than 40W due only to the power components losses of the amplifier. If the inductor is non-ideal, the amplifier will also deliver the active power (Joules losses and iron losses). This active power cannot be higher than the maximum power of the power supply (600W). -
Page 22: Rheostatic Braking
Vbus = 96V for the internal supply or 200V if an external supply is chosen. The resistance can’t be lower than 10Ω. It is up to the user to add margin on the ratings of the rheostat. CEDRAT TECHNOLOGIES Current Switching Amplifier 18/12/2017... -
Page 23: Buffer Capacitor Extension
In this case, it may be smarter to add a buffer capacitor extension rather than a rheostat as it would be smaller and more efficient. Ask Cedrat Technologies if the calculated energy needed is larger than 3.5J. CEDRAT TECHNOLOGIES... -
Page 24: Minimum Output Inductance Value
A conservative value for the inductances to be placed at the outputs of the amplifier is 2 x 50µH. The inductances should be placed in series with the actuator at both outputs. 8.3.6.Protections The CSA96 includes built-in protection against these fault conditions: Output over current. -
