Regulated DC/DC converter TPS-HVS1024S12

isolatedSIP-8for railway applications

Overview
The TPS-HVS1024S12 is part of the TPS-HVS10 series of DC-DC converters designed for industrial and rail transit applications. This compact SIP8 module supports wide input ranges for 24V and 48V systems, provides 1500VDC isolation and operates from -40°C to +85°C. Available output options include single outputs from 3.3V to 24V and a ±15V dual-output variant. The module supplies up to 10W with typical efficiency around 88%, integrated protections and a UL 94V-0 flame-retardant enclosure.
