DC Power for
Business-Critical Continuity™
MEDIA Inverter
1500VA – 48Vdc
Key Features
nDual input sources (AC & DC)
MEDIA is a compact and scalable inverter providing
a pure sine wave supply of AC power.
nCompact and lightweight solution
Description
nHigh efficiency
In conjunction with a DC power system, the MEDIA inverter delivers a reliable backup energy solution for AC applications. Using the latest Twin Sine Inverter (TSI)
technology, this inverter provides superior energy efficiency in a compact size.
nFull scalability and expandability
nNo single point of failure
The MEDIA inverter is designed to work from 230Vac and 48Vdc sources through
AC/AC and DC/AC conversions. Unlike traditional inverters, this inverter features an
AC to AC conversion process, known as Enhanced Power Conversion (EPC), that
double filters the output wave form. EPC mode operates offline, assuring high efficiency of 95% without any compromise in quality or stability. By filtering current
and voltage offline, EPC mode is able to operate like an online rectifier and inverter
but deliver significantly better efficiency. Compared to a UPS operating in offline
mode without current and voltage filtering, efficiency is the same but the rejection
of grid disturbances is much higher.
nTotal modularity as no external
static-switch required
MEDIA inverters have an in-built static switch function. Because no external static
switch is needed, the inverter system is smaller, more reliable and easy to expand.
As many as 32 inverter modules can be used in parallel.
nHot swappable
nPure sine wave on AC output
nTransfer time reduced to naught
An online mode is available for use during the occasional mains outage when inverters are fed by batteries. Since these inverters will almost constantly provide an
efficiency of 95%, they offer the most reliable AC backup solution in the industry!
Application
Inverter systems are normally used for AC backup requirements in a telecom / datacom site or anywhere a highly reliable AC power back up source is needed.
