1.  **PURPOSE.** This advisory circular (AC) contains a specification
    for constant current regulators (CCR) and a monitor for use with
    airport lighting circuits.

2.  **CANCELLATIONS.** AC 150/5345-10E, *Specification for Constant
    Current Regulators and Regulator Monitors, dated 10/16/84,* is
    cancelled.

3.  **PRINCIPAL CHANGES.** The following principal changes are in this
    specification:

    a.  The addition of Title 47, Part 15, Subpart B, Incidental
        Radiator, classification, and testing for conducted and radiated
        interference.

    b.  The addition of crest factor limit testing.

**c.** A change to the output current tolerance of a CCR to ± 0.1 amp
(A) for 6.6A and ± 0.3A for 20A.

4.  **APPLICATION.** The specifications contained in this AC are
    recommended by the Federal Aviation Administration (FAA) in all
    applications involving development of this nature. For airport
    projects receiving Federal funds under the airport grant assistance
    or the passenger facility charge programs, the use of this
    specification is mandatory.

5.  **METRIC UNITS.** To promote an orderly transition to metric units,
    this specification includes both "English" and "Metric" dimensions.
    The metric conversions may not be exact equivalents, and until there
    is an official changeover to the metric system, the English
    dimensions will govern.

# CHAPTER 3. EQUIPMENT REQUIREMENTS.

## 3.1 **General.** 

## 

The equipment requirements are grouped into four categories:
environmental, performance, detail, and monitoring requirements.

## 3.2 **Environmental Requirements.** 

The equipment must be designed for continuous operation under the
following conditions:

a.  Temperature range from -40 degrees to 131 degrees Fahrenheit (F)
    (-40 degrees to 55 degrees Celsius (C)).

b.  For monitoring circuitry, the temperature range is from 32 degrees
    to 131 degrees F (0 degrees to 55 degrees C).

c.  Relative humidity range from 10 to 95 percent.

d.  Altitude range from zero to 6,600 feet above sea level (2,000
    meters).

## 3.3 **Performance Requirements.**

###  {#section-11 .Style-Heading-3-+-Left}

### 3.3.1 **Regulation.** {#regulation. .Style-Heading-3-+-Left}

**3.3.1.1 Resistive Loading.**

The CCR must maintain the output current per Table 1 while powering any
load from short circuit to 100 percent load.

a.  For all CCRs, regulation must be maintained over the full range of
    environmental conditions specified in paragraph 3.2 and the input
    voltage range specified in paragraph 3.3.4.

## 3.5 MONITOR.

The monitor must detect the status of the CCR and the series lighting

    1.  A CCR without monitoring is designated Type L-828.

    2.  A monitor may be offered as a separate module designated type
        L-827.

    3.  If monitoring is added to a Type L-828 regulator, it becomes a
        Type L-829.

b.  The monitor must be matched with the CCR so it will function when
    the CCR is powering a load with a nominal value that is between 50
    and 100 percent of its rated capacity. The load must be a constant
    current loop that energizes the primary of isolating transformers
    that are specified in AC 150/5345-47, *Isolation Transformers for
    Airport Lighting Systems.* The secondary winding of the transformers
    will power airport lighting fixtures.

c.  At a minimum, the monitor must operate on the top two steps of Style
    1 (3 brightness steps) and Style 2 (5 brightness steps) regulators.

d.  The monitor must detect the following fault conditions:

Table 3. CCR Fault Conditions

  ----------- -----------------------------------------------------------
  Fault       Fault Condition
  Letter      

  a           Loss of ac input power to the CCR

  b           Shutdown of the regulator due to operation of protective
              circuits described in paragraph 3.3.10

  c           A 10 percent or greater drop in the volt-amperes (VA)
              delivered to the series circuit.

  d           Failure of the regulator to deliver the output current that
              corresponds to the brightness step selected (see Table 1).

  e           Failure of a preset number of lamps in the series circuit.
  ----------- -----------------------------------------------------------

e.  See Table 3. Faults a, b, and d must be detected at all brightness
    levels.

f.  The monitor must function when the regulator is in the remote or
    local control modes (fault "d" must be detected in the remote mode,
    but need not be detected in the local mode).

g.  The monitor must operate in a fail-safe manner and not cause the
    regulator to be inoperable or output incorrect currents.

h.  If it is required by the application, the output of the monitor must
    energize the coil of a single pole double throw (SPDT) relay when
    the regulator is operating properly.

    1.  The relay contacts must be rated for a 2 amp resistive load at
        120 Volts ac, 60 Hz.

    2.  The monitor outputs must be connected to a terminal block to
        allow external connections and operate with control lines
        similar to those described in paragraph 3.4.6.

i.  Upon the initial detection of a fault, the monitor must delay 5.0
    seconds (except for fault "a" and "b" in Table 3) before the fault
    is displayed. If the fault still exists after 5 seconds, the monitor
    must indicate an alarm.

j.  A visual indication must be provided on the monitor to indicate
    which monitored parameter caused the fault indication (except for
    fault "a").

k.  A regulator "on" light must be provided on the monitor.

l.  The load of each monitored airfield lighting system lamp and its
    associated isolation transformer may vary between 10 and 200 watts
    within the following:

    1.  All fixture loads and transformers must be the same.

    2.  There cannot be devices on the series circuit which will cause
        the load to vary greatly (signs with fluorescent ballasts/lamps,
        power adapters, signs with printed circuit board assemblies,
        etc.).

    3.  Film disc cutouts must not be used since they will cause a load
        different than an open circuit series to series transformer.

**m.** The monitor must be adjustable so the number of failed lamps
required to cause a failure indication may be from 4 to 10 when the
series loop is loaded with identical wattage lamps. For mixed wattage
bulbs on the same series loop, a loss of 10% or more CCR load must be
detected.

**n.** After the preset number of monitored lamps fail, it must be
possible to switch the monitor into a degraded operation mode.

**o.** When in the degraded operation mode, the monitor must deactivate
the fault indication and reactivate it upon the failure of an additional
preset number of lamps (1 to 5).

**p.** Additional monitor warnings or alarm levels may be optionally
provided by the manufacturer, but are not required.

**Note:** *When a CCR is connected to a computerized airfield lighting
control monitoring system (ALCMS), the optional monitoring points may be
required for reporting Remote/Local Status and Primary Power (ac power
loss to the CCR). See AC 150/5345-56, Specification for L-890 Airport
Lighting Control and Monitoring System (ALCMS), for additional
information.*
