Description

The Gaia Converter transient suppressor LGDS-100 is an ultra-compact front-end power module designed to allow operation during voltage transients and spikes, occurring in avionics or military systems. The LGDS-100 delivers an output voltage adapted to Gaia Converter DC/DC modules. This module is optimized to provide high power efficiency up to 98%.

Model:

Gaia's LGDS-100 High-Reliability Transient suppressor is designed for higher operating temperatures of -40 to +105°C (optional -55°C) for typical military & airborne applications:

LGDS-100-P-K

Available Options (see specs for details):
• T = -55°C Start-Up Temperature
• S = Screening & Serialization

Modes of Operation

The LGDS-100 features 3 modes of operations as follows:

Normal operation: Normal operation occurs when the input voltage is within the permanent range (9-42V) . The LGDS-100 is then operating in steady transparency state.

Transient operation: The LGDS-100 clamps input transient up to 202V/350ms, or 101V/400ms, and keeps it's output at 42V or less. The LGDS-100 series is compliant with the inter-national input bus standards

DEF-STAN-61-5 Part 6 Issue 6,
MIL-STD-1275A/B/C/D,
MIL-STD-704A/D/E/F,
AECMA EN2282,
GAM-EG13B/AIR2021E,
DO-160C/D/E/F/G.

Power fail operation: When a failure occurs such as an under-voltage, an over current or an over temperature, the LGDS-100 turns to power fail mode and stops operation until the failure is removed. The LGDS-300 features 3 protection functions : input under-voltage lockout (UVLO), output over current protection (OCP) and over temperature protection (OTP).
