DDA-6V40 40A, 660V max, 4-32 VDC activated
Please note: the above
models are being phased out, due to the lack RoHS compliance. A suitable
replacement is one of the following:
- HDA-3V25E-HS1.6 for applications
up to 277 VAC, 25 amps (about 1 inch wider than a DDA-6V25), shown at:

Internal
MOV |
The
5V model uses an internal MOV that is similar to the Littelfuse Harris V575
LA80B Metal Oxide Varistor. The use of MOVs is encouraged in situations where
there are frequent voltage surges such as motor starter applications. For
example: for motor starters, you can use a DDA-6V25 AND an external
MOV_V575LA80B
(click to buy) OR you can purchase a DDA-5V25, and the
MOV will be inside the unit. Contact Power-io for price and availability of
this custom variation. |
