Driver Crosses
what does CC and CV stand for?
Constant Voltage and Constant Current
What are our two types of ballasts
instant start and rapid/programmed start
True or False,
All EM drivers use batteries
True
what are the 3 wiring configurations
series, parallel, series-parallel
customer has an LED driver cross they need.
specs are 850mA, 42VDC. which driver would be the best cross?
(hint: there are two possible options)
T1M1UNV105P-40E or T2C1UNV150P-40L both programmed to 850mA
what is the output current of SHS14-UNV-H
425mA
What is the standard EM runtime for all EM products?
90 minutes
An LED driver can be both UL listed and UR recognized, True or False
False
Customer is looking to cross part number:
701507-60W2 SloanLED
they want an identical cross. what can we recommend?
T1UNV012V-60LG
How do you calculate Lamp Voltage?
(hint: remember the equation P=V*I)
Lamp power divided by Lamp current
P/I-V
What type of UL certification does our FHS2 have?
it is a UR recognized component
T1M1UNV210P-60LES has what type of classification
CE
Customer is looking to cross a driver
output specs are as follows:
1.9A output CC
10-50VDC
95W Max
what is the best cross?(hint: we will not have one single option to cover the entire range)
T1M1UNV21P-60L or T1M1UNV240P-96L depending on load information
Customer is looking to find a ballast for their lamp. they are using a 30W 425mA lamp. one lamp will be used what is the best cross for this application?
SHS1-UNV-C or SHS1-UNV-C-I
I have a customer who wants to find an EM driver for their application? their driver is 25VDC 3.3A output. why would this not work with our FHS2?
passthrough limitations are exceeded
I have a series module configuration of 5 modules. each module has a forward voltage of 32VDC. i am outputting 1.3A Constant current to the modules. what is my total power consumption.
What is 208W
32VDC per module * 5 modules =160VDC total
160VDC * 1.3A=208W
What are the specifications/information needed to match a driver? (hint: there are 5)
a. Output current
b. output voltage range
c. max rated power
d. misc features(IP rating, aux output, classifications, dimming, form factor)
e. CC or CV
Customer is looking for a lamp cross. they provide a lamp voltage of 124V and a lamp power of 155W. they are looking to power two lamps. what is the operating current, and what would be our best recommendation?
the lamp current is 800mA, and the best cross is SHS15.
We have a customer using a FHS2 and is looking to achieve a run time of 180 minutes with 1400 initial lumen output. their system efficacy is 175lm/W. what is the minimum battery wattage needed to achieve this?
What is a 16W battery.
reasoning is: 1400 lumens divided by 175lm/w=8W for 90 minutes EM. double the power to double the EM time
Which Two UL standard must our DirectAC Engines meet for certification?
What is UL 1598C and UL8750
