The LGDS-50 delivers an adapted output voltage compliant with Gaia 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 4W and 50W 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 Gaia Converter automated test equipment. The LGDS-50 features 2 modes of operations as follow : * Normal operation : Normal operation occurs when input bus line is in steady state permanent range. The LGDS50 is then operating in steady transparency state providing an output with a typical 1,5V drop-out voltage. * Transient and spikes operation The LGDS-50 can sustain both : * transient during 1s and 20 ms according to RIA12 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, RIA12 or IEC 571. 2-Product Selection Single output model : LGDS - 50 - Input Voltage Range input output Output Permanent J : 10-36 VDC Q : 36-154 VDC REDEFINING THE SOURCE OF POWER (c) Gaia Converter FC97-025.01/10 Revision J For locations, phone, fax, E-Mail see back cover K 5 LGDS-50 Series Industrial Grade 3- Modes of Operation 3-1 LGDS-50 Modes of Operation * Normal operation : During normal operation the module is operating in steady transparency state. The LGDS-50 series features 3 modes of operations detailed hereafter and illustrated by the 2 figures which depict the transfer fuctions for both models LGDS-50-J-K and LGDS-50-Q-K : * Transient and spike operation : The LGDS-50 series can sustain input transient and spike describe in section 3 by a clamping input system. * Power fail operation : An undervoltage lock-out stops operation for input voltage below the low line operation threshold (typically 10Vdc).
