Pressure Independent VAV Applications with CEP/CSP-4000 Series 44 CTE-5202 Applications Guide, AN0912A Rev. D

9.1 VDC vs. 24 VAC Power Options

The CTE-5202 can operate from the 9.1 VDC output

supplied by the CEP/CSP-4xxx, but AO1 and AO2

will not be able to aain a full 6 VDC (e.g., a maxi-

mum of about 5.3 VDC) output to the 0–6 VDC CEP/

CSP-4xxx inputs. This means the maximum air ow

controlled by the CEP-4xxx can be only around 2000

fpm instead of 3000 fpm. However, this will still

cover nearly all applications.

(See the Voltage/Velocity Correlation chart in the

CEP-4000 Series Applications Guide.)

OR (but NOT Both)

If more than about 2000 fpm is required, use 24 VAC

from a transformer to power the CTE-5202. This can

easily be done by connecting the ~ terminal on the

CTE-5202 to Terminal 10 (24 VAC, phase) on the

CEP-4xxx instead of Terminal 5 (+9.1 VDC).

CAUTION

Connect the CTE-5202 to the CEP-4xxx’s

Terminal 5 OR 10, but not jumpered to both.
