TDK HFE3500 Front-End Power Supplies

TDK-Lambda HFE3500 Front-End Power Supplies are 3500W AC-DC industrial devices that can be operated in a hot-swap redundant configuration and used to provide up to 13.3kW of bulk power in a single 1U rack. Each 19” 1U high rack fits up to four power supplies, and three full racks can be paralleled for a single-output configuration. These power supplies feature internal O-ring MOSFETs and current share for automatic parallel operation. Communication is possible via the built-in isolated PMBus™ (I2C) interface or LAN option. TDK-Lambda HFE3500 Front-End Power Supplies come with AC fail, DC good, remote on/off, remote output adjust, and a 5V or 12V auxiliary output.
