Emerson Network Power has showcased a new family of standard power supplies for LED lighting, the LDS70 series at the Electronica 2010 global electronics trade fair.

The off-the-shelf, low-profile solutions are designed to support system life requirements greater than 70,000 hours and help manufacturers meet time-to-market demands and quality requirements.

The new 70 watt family supplies provide both constant-current and constant-voltage modes, enabling customers to simplify inventory management.
 
Constant-current mode features programmable current levels; constant-voltage mode has no-load to full-load operation. Current levels can be preset by the system designer or adjusted in application to perform dimming functions. The narrow, low-profile form factor of the LDS70 series allows customers to reduce light fixture size or locate them in small areas of their system. Both 12 V and 58 V models have no minimum load requirement and are comprehensively protected against short-circuit, overvoltage and overtemperature situations.
 
An IP67 rating makes the Emerson Network Power LDS70 series an excellent choice for use in applications where the ingress of dust or moisture is a concern. The ability of the product to operate from minus 40 to 60 degrees Celsius makes the family ideal for both indoor and outdoor use.
 
The LDS70 series comply with critical safety specifications and regulatory requirements - including EN 61347, UL 8750, and CSA C22.2 No. 107.1 and CE LVD directives.
 
It operates a wide input voltage range of 100 to 240 Vac (U models) or 120 to 277 Vac (H models) and is equipped with active power factor correction rated at 0.9 typical to minimize input harmonic current distortion.

The flexible nature of the LDS70 design platform also facilitates rapid modification for customer-specific applications.
