Strobe Light Ratings
The signaling strobe is rated for 0
°
to 49
°
C and is not suit-
able for outdoor use.
See Figure 3. The light output of the SP10**24LO is 1.5 cd
minimum when it is viewed from the front. The light out-
put of the SP10**24M is 15 cd minimum when it is viewed
from the front.
Under no circumstances can the strobe input voltage ex-
ceed 33 VDC or be less than 18 VDC.
To calculate battery requirements, use the current values
shown in Table 2. However, note that there is an in-rush
current associated with strobe power-up. This information
may be used in consideration of fuse selection.
For the 24V strobe, as shown in Figure 4, the in-rush cur-
rent typically peaks at 7.0A, then drops to nominal in
800
