Emerson Network Power adds 100W Version to its LED Lighting Power Supply Series

A new series of high efficiency power supplies for LED lighting, the LDS100 series, is being announced today by Emerson Network Power, a business of Emerson and the global leader in enabling Business-Critical Continuity™. The company’s LED lighting products now cover three distinct power output bands – 25, 70 and 100 W – making it easy for original equipment manufacturers and system installers to obtain the optimum high quality power supply for their application.

LDS100 Specifications:
Total Max Power: 100 W
Total Max Current: 4.1 A
Input Voltage: 100 V to 277 V
Output Voltage: 24 V
Outputs: Single
Size (L x W x H): 8.460" x 1.650" x 1.180"
Operating Temperature: -40 °C to 90 °C

The new Emerson Network Power LDS100 series 100 watt LED power supplies offer a choice of models –featuring an input range of 120 to 277 Vac (H models), and an input range of 100 to 240 Vac (U model). The first models in the series feature Class 2 outputs capable of delivering up to 4.1 A at 24 Vdc, and offer both constant current and constant voltage output modes, enabling customers to meet the demands of different LED lighting systems with a single model, thereby minimizing inventory. Constant voltage mode operates from no load to full load. The LDS100-24-H03 model features programmable current limit levels, controlled via an IEC 60929 compliant interface using a standard 0 to 10 V signal, to support dimming. The current limit level is also resistor programmable and can be preset by the system designer.

All Emerson Network Power LDS100 power supply models feature active power factor correction rated at 0.9 minimum to support Energy Star requirements and meet the class C harmonic requirements of IEC 61000-3-2. The supplies also have a very high conversion efficiency – typically 90 percent when operating from a nominal 230 Vac input – which further helps minimize users’ running costs. They are rated for operation over a wide case temperature range of minus 40 to 90 degrees Celsius, without forced air cooling. Available with ingress protection ratings as high as IP67, which provides protection against shallow water immersion, LDS100 power supplies are intended for outdoor and ruggedized indoor applications. Housed in a slimline package measuring just 8.5 x 1.65 inches (215 x 42 mm), with a height of only 1.2 inches (30 mm), the power supplies are easy to accommodate in modern LED lighting fixtures with limited space.

Emerson Network Power LDS100 series power supplies comply with the CISPR 15 requirement for EMI and meet FCC part 15 conducted noise standards. They are protected against short-circuit, overvoltage and overtemperature conditions. The surge immunity performance of the LDS100 series has been evaluated to installation class 3 (U models) and class 4 (H models) test levels set out in IEC 61000-4-5.

Critical safety specifications include EN 61347-2-13 and UL 8750, which are specific to LED related applications, and the LDS100 series also complies with CSA C22.2 No. 107.1 and CE LVD directives.

The flexible nature of the LDS100 design platform also facilitates rapid modification for customer-specific applications.

Emerson Network Power’s LDS100 series 100 watt LED power supplies are available now. For more information, please see the LDS100 series website or download the datasheet.
