Campbell Scientific DCDC18R Boost Regulator - Manual (Page 6)

DCDC18R Boost Regulator
This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is
operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be
required to correct the interference at his own expense. Note
* The slow start boost regulator typically starts to work at a supply voltage of
about 10 volts. Supply voltages below 10 volts pass directly to V out (through
2 Schottky diodes dropping the voltage by ~ 0.6 volts). With the DCDC18R
operating at the maximum output current (18 V * 1 A = 18 W) the input power
required is up to 18 W / 0.8 efficiency = 22.5 watts; that is the maximum
current specification of 2.25 Amps at 10 volts.
