Pure sine wave inverters meet rail standards
A series of pure sine wave inverters, which provide up to 3000VA of power, has been released by Schaefer. The PRP-3000 series of inverters features models that meet industrial and rail standards. Standard input voltages of 24, 36, 48, 72 and 110VDC are inverted to adjustable 120VAC or 230VAC outputs that are regulated to 4% or better. Units can be configured for three phase synchronisation.
All models in the PRP-3000 series feature overload protection and an LED indicator for output OK or alarm conditions. A wide operating temperature of –25 to +70ºC allows for installations in extreme conditions and meets EN50155 Class 3. Remote inhibit and remote off are standard in the PRP-3000 design. Units are highly efficient, with ratings ranging from 88 to 92%. Emissions to EN61000-6-4 and EN60121-3-2 meet both industrial and rail standards and minimises interference to other sensitive equipment. Status and programming is controlled through the RS232 interface.
The PRP-3000 inverters, which can be customised, are available now, priced at $2375 and sold in 50-piece quantities.
