hot swap power supply

Multinational electronics company TDK Corporation has recently expanded its TDK-Lambda HFE1600 range of 1.6kW high-density, front end power supplies with the addition of a 32V model.

The HFE1600-32 front end power supply from TDK is designed for broadcast applications and operates from a universal 85 to 265Vac input, and the high efficiency of up to 92 per cent minimises heat dissipation and power consumption thus meeting Climate Savers Computing efficiency standards. It is also well-suited for use in applications including communications, servers, lasers, and process controls.

In addition to the 32V model, these supplies are available with other standard output voltages including 12V, 24V, and 48Vdc. The outputs are user adjustable to suit custom requirements.

Each supply has two variable-speed cooling fans and can operate in temperatures ranging from -10°C to +70°C.

As with all models in the series, the HFE1600-32 AC-DC power supply can be used individually or up to 5 units can be mounted into a dedicated 1U rack delivering up to 8kW. To form a hot swap N+1 redundant power system, up to 10 units mounted in two racks can be configured in parallel with single wire current sharing.

TDK-Lambda has also integrated a keying system to prevent mis-insertion of modules into adjacent racks of differing voltage. Output voltage is programmable by resistance, external voltage or optional PMBus compatible I2C communication interface.

These hot swap front end power supplies comply with EN55022 and FCC Class A radiated and Class B conducted emissions and meet IEC61000-4 immunity. All models are safety approved to EN/IEC/UL 60950-1 edition 2 with CE mark and are backed by a three-year warranty.

± SENSE lines

Figure 3: Shown here is the capability of the ± SENSE lines that will ensure that there will be minimal voltage drop to the load especially when it is a distance away.

The power supplies are priced from $399.00 each in quantities of 500 units. For more information go to the TDK-Lambda website
