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.

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.
