LOW TEMPERATURE MODIFICATION
LCD display limits controller operating temperature range to –20 °C to + 70 °C even if the other electronic components work in wider temperature range.
Internal preheating foil is mounted in InteliLite LT to extend display operational temperature range.
Preheating starts at temperature below 5 °C and preheating power depends on temperature and power supply voltage.

TECHNICAL DATA
Operating temperature:-20°C to +70°C(IL-CU  Standard); -30°C to +70°C(Order code:IL-CU-LT)
Storage temperature:-30°C to +80°C(IL-CU  Standard); -30°C to +80°C(Order code:IL-CU-LT)
Preheating foil increases controller current consumption
No preheating:360mA(12VDC);230mA(24VDC);100mA(36VDC)
Preheating at ambient temperature(0°C):+50mA(12VDC);+25mA(24VDC);+20mA(36VDC)
Preheating at ambient temperature(-15°C):+180mA(12VDC);+85mA(24VDC);+150mA(36VDC)
Preheating at ambient temperature(-30°C):+20mA(12VDC);+65mA(24VDC);+100mA(36VDC)
InteliLite LT works immediately after switch on at -30°C and display becomes visible after a few minutes.
Short-term voltage drops (e.g. during the engine cranking) do not affect the operation at all.
