ERG’s SFW Series Inverters Offer a
Range of Advantages over the Competition:
- Wider input voltage range
- Guaranteed 1500 V strike over the entire
range of input voltages.
- SFW Series inverters will easily dim to
less than 5% brightness (compared to only
16% for some competitive inverters)
- SFW Series inverters run more
efficiently because they run on only one
power conversion stage as opposed to the
double conversion stage topology (buck
followed by a Royer circuit) used in
competitive inverters. SFW Series inverters
typically run at high efficiency.
- SFW series inverters operate down to -30
degrees Celsius
- Lower Profile: The SFWA/SFWB series
inverter is less than 6 mm high (Compared to
8 mm for some competitors)
- The SFWE/SFWF series inverter is less
than 10 mm high. (Compared to 12 mm for some
competitors)
- SFW Series inverters use one stage of
resonant switching for the power
transformation, which creates a very low EMI
waveform with well below 10% THD, typically
in the 4 to 6% range.
- ERG can modify the SFW series inverters
to run off of an external PWM signal for
dimming and can also reverse the onboard
dimming slope; competitive inverters can
only run off of an external voltage to
modulate the output current (PWM dimming is
not possible).
- SFW Series inverters have an open lamp
detection feature that will disable
operation if a load opens. (This will
prevent sustained high voltage at the output
connector).
Talk to an ERG engineer to see how the SFW Series inverter that’s right for your application stacks up against what you’re using now.
