• output noise: 30 mV_pp without load, 10 mV_pp with a load of 10 µF

Security

• interlock loop: two pins at the output connector, short circuit enables the amplifier
• overcurrent protection: output current limiter
• overtemperature protection:
  • temperature sensors at the heatsink
  • temperature sensor PT1000 at the actor, (shutdown and restart temperatures freely programmable)
