Compact Power for 48 V Systems: ABLIC S-19230/1 BU Voltage Regulators
The major challenge in developing modern vehicles:
An increasing number of sensors, control units, and communication interfaces must be reliably powered – all within increasingly complex 48 V on-board networks.
Here, the quality of voltage regulation determines safety, efficiency, and service life. This is precisely what the S-19230/1 BU from ABLIC (distributed by GLYN) was developed for.
The S-19230/1 BU is a high-precision linear voltage regulator, specifically designed for operation in 48 V automotive electrical systems. With a voltage tolerance of up to 80 V, extremely low self-consumption, and an integrated open-loop protection circuit, it provides maximum safety – even under the most demanding conditions.
All advantages at a glance:
- Direct connection to 48 V on-board networks – no additional pre-regulator required
- Simplified circuit design thanks to a reduced number of components
- Minimal standby current – ideal for parking mode
- Integrated open-loop protection for increased safety with variable output voltage
- Compact and reliable power supply for sensors, CAN, and LIN transceivers
The regulator solves a central problem of modern vehicle electrical systems: ensuring stable and efficient power supply to sensitive components, even at high input voltages. At the same time, its extremely low quiescent current helps save energy and improve overall vehicle efficiency.
Tailor-made solution for the mobility of tomorrow
With the S-19230/1 BU, ABLIC offers a tailor-made solution for the mobility of tomorrow – robust, compact, and energy-efficient.
And for those with similar requirements in industrial applications, the S-1230/1 variant is available. It impresses with up to 66 V input voltage, +105 °C temperature resistance, and output currents of 100 mA or 200 mA.
Whether automotive or industrial – ABLIC ensures reliable performance in every environment.
Perfect for modern mobility – and beyond.
