Converter DC/DC range of modules. This line of module is optimized to provide high efficiency up to 98% over the whole power range between 4 W and 75 W power.
The module includes also an EMI filter to provide compliance with EN55022 Class A together with GAIA Converter DC/DC modules.
The module is manufactured in a fully automated process to guarranty high quality. Each module is tested with a
Converter automated test equipment.
The LGDSI-75 features 2 modes of operations as follow:
Normal operation occurs when input bus line is in steady state permanent range. The LGDSI-75 is then operating in steady transparency state providing an output with a typical 1.5V drop-out voltage.
Transient and spikes operation
The LGDSI-75 can sustain both:
transient during 1s according or EN50155 requirements,
high spike levels up to 1.8kV with 5 Ohms impedance and 8.4kV with 100 Ohms impedance to meet international input bus standards of EN50155.
