Leads meet high safety standards

Fluke ’s new ultra-ruggedTL 175TwistGuard test leads are a world- first - featuring a manually adjustable guard. The patented Twist-

Guard extendable tip shroud meets the highest electrical safety requirements to reduce tip exposure while providing the versatility needed for most measurements. Simply twisting the test lead cuts the exposed probe tip length from 19 to 4 mm. Extra-heavy duty strain relief on both probe-end and plug-end has, remarkably, tested beyond 30 000 bends without failure! WearGuard double insulated silicone leads ensure added safety as each lead has two silicone insulation layers: red or black on the outside and white inside. Any white showing through warns of nicks or scuffs in the insu- lation.The double insulation also means they can withstand high temperatures and remain flexible in cold temperatures.The leads are CAT II 1000 V (extended) or CAT III 1 000 V and CAT IV 600 V safety rated (retracted). Universal input plugs are compatible with all instruments that accept standard 4 mm shrouded banana plugs. Enquiries: Comtest Distribution.Tel. 010 595 1821. Visit www.comtest.co.za

Buck-boosted constant current LED driver

Mean Well has introduced a buck- boost-type dc-dc potted module type constant current LED driver - LDB-L/LW series. This series offers multiple models of different current levels, 300 mA /350 mA/ 500 mA/ 600 mA. A very wide I/O range is provided and regardless of the voltage dif- ference between output and input, the drivers operate ideally. With the built-in EMI filter, LDB-L/LW complies with the lighting standard EN55015 without the need for addi- tional external anti-electromagnetic components. In addition, the potted design makes it workable in a harsh envi- ronment with high dust and high moisture. The LDB-L/LW series is recom- mended for the LED lighting mod- ules, such as street lighting, land- scape lighting, tunnel lighting, household lighting, and backlight- ing.
