- short-circuit – in case of overload or short-circuit, the output voltage is automatically disconnected. The power supply cyclically attempts to turn on the power supply and when the cause of the protection operation ceases, the rated supply voltage is restored;
- overvoltage – cut off the output voltage. Return to normal operation is possible after turning the power off and on again;
- thermal – cutting off the output voltage. When the temperature drops to a safe value, the output voltage will be restored.
Implementation
| Type | Output voltage | Output current |
| ZI-100-12 | 12V DC | 8,3A |
| ZI-100-24 | 24V DC | 4,15A |
