*1 80 µs cannot be selected when the LV-S31/S62/S63 is connected
*2 Input time is 25 ms (ON)/25 ms (OFF) when external calibration time is selected.
*3 These numbers double when "DOUBLE" is selected.
*4 Use with the over current protection device which is rated 30 V or more and not more than 1 A.
*5 To connect more than 9 units, the power voltage must be 20 V or more.
*6 Increases 30 mW (1 mA) for HIGH SPEED mode.
*7 It increases by 15% when connected to the LV-NH100/NH110/NH300. It does not include the power consumption of the load.
Power consumption when expansion units are connected is the total power consumption of each amplifier unit. Example: When one main unit (LV-N11N) is connected to 2 expansion units (LV-N12N) and they are used with LV-NH100 heads in HIGH SPEED mode.
(1.15 × 860 mW × 1) + (1.15 × 860 mW × 2) = 2967 mW max.
*8 If more than one unit is used together, the ambient temperature varies with the conditions below. Mount the units on the DIN rail with mounting brackets and check that the output current is 20 mA or less for a unit.
One or two more units connected: -20°C to +55°C -4°F to + 131°F; 3 to 10 more units connected: -20°C to +50°C -4°F to + 122°F; 11 to 16 more units connected: -20°C to +45°C -4°F to + 113°F. When using 2-outputs, one unit is counted as two units.
