L-828 CCRs LC-Type (4, 7.5, and 10 kW/6.6 A/60 Hz)

Description

Regulation

Environmental Operating Conditions

Refer to Table 2-8 for output current limits. Current regulation is obtained under the conditions listed in Environmental Operating Conditions.

The L-828 CCRs (4-10 kW/6.6 A) are designed for indoor use only in an area with adequate ventilation for cooling the constant current regulator. The environmental operating conditions include temperature range, relative humidity, and altitude.

 

Temperature Range

 

Without monitoring circuitry: -40 to +55 °C (-40 to +131 °F)

 

With monitoring circuitry: 0 to +55 °C (-18 to +131 °F)

 

Relative Humidity

 

0 to 100% (noncondensing)

 

Altitude

 

Sea level to 6,600 ft (2000 m)

Protection Devices

L-828 CCRs have the following protection devices:

 

Output open-circuit protection

 

Output overcurrent protection

 

Lightning arrestors on output terminals and bushings

 

Fuse protection of remote control supply voltage (48 Vdc and

 

120 Vac), and power supply for printed circuit board

 

Input breaker for supply voltage

 

W VA (load wattage in excess of maximum available volt-amperes

 

Open-Circuit Protection

 

The regulator includes an open-circuit protective device to open the

 

primary switch within 2 seconds after an open circuit occurs in the

 

secondary. The device resets within 2 seconds after the control

 

switch is turned off and re-energized, and cannot be tripped by

 

switching the load circuits or other transients.
