Protections*
Input
• Inrush Current Limiter – peak value of 2.5x Iin for less than 40ìSec
• Under Voltage Protection – unit protects itself (no damage) below 17VDC
• Over Voltage Protection – unit protects itself (no damage) above 82VDC
Output
• Electronic Over Voltage Protection –
Internal control protects unit (no damage) 10% above nominal voltage.
• Current limiting –
Continuous protection (10-30% above maximum current) for unlimited time (Hiccup)
General
• Over Temperature Protection:
Shutdown at base plate temperature of +105°C (±5°C)
Automatic recovery at base plate temperature lower than +95°C (±5°C)
* Thresholds and protections can be modified / removed – please consult factory.
