The HWS-L/BAT supplies are designed to charge secondary batteries (e.g., Lithium Ion, Lead Acid, etc.) that are employed in emergency power backup systems. They can also be used in applications that require a constant current source such as UPS battery charging, wastewater treatment, electrolysis, etc.

HWS1000L-BATThese supplies are ideal for small to medium emergency backup systems that use rechargeable batteries with a nominal voltage of 24V or 48VDC. Their design is based TDK-Lambda’s well-established HWS series of power supplies, which have been used extensively in the industrial equipment market. Since these supplies can operate in a parallel mode, a wide range of battery capacities can be accommodated.

These power supplies include embedded trim potentiometers for adjusting the charge current and maximum output voltage, which make them compatible with most types of rechargeable batteries. Each supply has a low profile of only 2.4 inches. The operating temperature range is from -20 up to +74°C. In addition, they feature a low-temperature start-up capability with a 100% load, as low as -40°C; making these a reliable choice for systems that experience extremes of temperature such as outdoor enclosed equipment. In addition, these power supplies include temperature-controlled fans, which minimizes acoustic noise (up to 8 dBA less than competitive units) under typical operating conditions.

Each model accepts a wide input power range of from 85 to 265VAC, making them compatible with global power standards. Other important features include a 12V@ 0.1A auxiliary output, DC Good & Fan Fail alarm and the ability to be paralleled connected to other units for higher current applications. TDK-Lambda has included protections for over-voltage and over-temperature conditions.

The HWS-L/BAT power supplies are available now and economically priced from $365.00 each in quantities of 100 units. More information about these supplies is available at: or call TDK-Lambda Americas at 1-800-LAMBDA-4.
