Y1 12V/24V to 28V 4A Boost Voltage Regulator — NonIsolated Quick overview A compact boost voltage regulator (model Y1) that converts a 12V or 24V DC source to a regulated 28V DC output with up to 4A output current. Designed for systems where isolation is not required, this converter provides a reliable way to power 28V devices from common 12V or 24V supplies. Key benefits — why you need it Power 28V loads from common DC sources: eliminates the need to equipment or carry separate 28V power supplies when only 12V or 24V batteries or rails are available. Stable regulated output: provides a fixed 28V output suitable for devices that require a steady supply voltage. current capability: supports up to 4A output to run moderatepower loads without additional converters. Simple integration: nonisolated design simplifies wiring and grounding when input/output common ground is acceptable. What makes it unique Model Y1 focuses on straightforward DCDC boosting from 12V/24V to a regulated 28V at up to 4A, providing a direct and reliable solution for systems that require a 28V rail but operate from lowervoltage DC sources. Key attributes Model: Y1 Functionality: Stepup (boost) DCDC voltage regulator / power converter Input voltage: 12V or 24V DC sources (designed for use with either nominal 12V or 24V systems) Output voltage: Regulated 28V DC Output current: Up to 4A continuous Isolation: Nonisolated (input and output share a common ground) — suitable where isolation is not required Practical considerations Use where a common ground between source and load is acceptable; the nonisolated design is not suitable for applications that require galvanic isolation. Verify that the input source can supply the required current and that wiring and connectors are rated for the expected current. Confirm that the target load tolerates a regulated 28V input and that inrush or startup currents do not exceed the converter's limits. Typical applications Automotive and marine: Power 28V communication or control modules from a vehicle or boat 12V/24V battery system. Industrial automation: Provide a 28V rail for sensors, actuators, or control electronics when only 12V or 24V DC supplies are present. Field and mobile equipment: Run 28V test instruments, lighting modules, or small motors from portable 12V/24V power sources. Ordering and identification Referred to as model Y1: a dedicated 12V/24V to 28V, 4A boost regulator with nonisolated topology. Notes This device is a nonisolated boost converter; ensure grounding and safety requirements for your application are met before installation.
