HiTek Power Introduces Versatile Power Supply Family

February 12, 2006 by Jeff Shepard

HiTek Power has introduced the HTK series of single-output, low-voltage, switch-mode power supplies. These power factor corrected units offer a wide choice of case type, output connectivity and front panel coupled with a choice of 11 output voltages between 3.3 and 54V.

The HTK300 units offer a maximum output power of 198W for the 3.3V variant and 300W for all other variants. The HTK400 supplies have a maximum output power of 400W, except the 3.3V unit, which has a maximum output power of 264W. The supplies accept an input between 90 and 264V and have a typical active power factor correction to 0.99.

All the supplies in the series are available in enclosed, U-channel and open-frame variants. They are offered without a front panel or with a choice of four options — IEC inlet only, terminal block only, power switch and IEC inlet, or power switch and terminal block. The output connector can be a barrier type terminal block, euro type terminal block or a Molex type connector.

The supplies feature over-current, over-voltage, over-temperature and short-circuit protection. A single-wire current share feature ensures that when the supplies are connected in parallel, the individual units share the output current to within ± 10% of each other. A power-good TTL signal will go low at least 1ms before the output goes out of regulation due to loss of ac input.

HiTek Power designs and manufactures low- and high-voltage power supplies that provide complete custom solutions for a wide range of original equipment manufacturer applications.
