The National Instruments SCXI-1383 is a compact float charger and 13.8 VDC power supply specifically designed for industrial automation applications. It features a versatile input voltage range of 100 to 240 VAC and operates at a frequency of 50/60 Hz, making it suitable for a variety of power environments. With dimensions of 16.5 x 8.0 x 5.7 cm, the SCXI-1383 can be integrated into areas with limited space. This power supply delivers a stable output voltage between 13.8 and 13.95 V, ensuring reliable functionality for connected equipment, such as the SCXI-1000DC chassis. It is capable of providing a charging current of 3.7 to 4.5 A, allowing for the efficient recharging of the SCXI-1382 battery pack within 12 to 14 hours.

Safety features include short circuit and reverse polarity protection, as well as an auto-recovery circuit that guards against overcurrent conditions and an integrated fuse for enhanced reliability. The SCXI-1383 serves three primary functions: powering the SCXI-1000DC chassis, charging the SCXI-1382 battery pack, and enabling continuous operation by float charging the battery while simultaneously supplying power. A green LED display clearly indicates power availability, charging status, and alerts users to conditions such as a fully charged battery or the need for maintenance. This device complies with stringent safety standards for electrical equipment used in measurement, control, and laboratory environments, including IEC 61010-1 and UL 3111-1, ensuring minimal electromagnetic interference from surrounding electronic equipment.
