Product Description:
HLB01.1C-09K0-N03R4-A-007-NNNF is a DC bus resistor. It provides several advantages for industrial applications, including increasing regenerated power, improving peak regenerated power, and quick DC bus discharge. Weight of the unit is approximately 5.8 kilograms. The permitted input voltage range is 254 to 750 Volts DC. The specified braking resistor threshold is 820 Volts. Continuous power rating of the HLB01.1C-09K0-N03R4-A-007-NNNF resistor is 1 kilowatt. The peak power rating is 100 kilowatts. Nominal power rating for the unit is 9 kilowatts. The maximum regenerative power is 100 kWs. If multiple devices are connected in parallel, the unit suffers from 0.8 derating. The control voltage supply is 19.2 to 28.8 Volts DC. Power consumption of the control circuits is 14 Watts and the maximum inrush current is 3 Amps for 50 milliseconds.
Mounting depth for the HLB01.1C-09K0-N03R4-A-007-NNNF resistor is 300 millimeters. Its resistance is 3.4 Ohms and the DC bus carries nominal voltage of 700 Volts DC. Staff working on this high-power unit can get a lethal electric shock. Therefore, suitable precautions must be taken for safety of working personnel. The resistor must be disconnected from input power and personnel must wait for at least 30 minutes for discharging. A discharging device can be used to shorten the waiting time. Personnel must ensure voltages are less than 50 Volts before working on the unit. Overload and short circuit protection are provided by fusing elements on the main input power connection. The recommended tightening torque for the input power is 5.5 Nm. A grounding connection point located near the bottom at the front side must be connected to equipment grounding system at the installation site. Protection class of the resistor is IP20.
