70W LED-lighting supplies support more-than-70,000-hour lifetime

摘要

The 70W LDS70 LED-lighting standard power supplies support lifetime requirements greater than 70,000 hours. The devices provide constant- current and constant-voltage modes. Constant-current mode features programmable current levels; constant-voltage mode has no-load to full-load operation. Both 12 and 58V models have no minimum-load requirement and have comprehensive short-circuit, overvolt-age, and overtemperature protection.
