Safety
FCC PART 15 Information Note:This equipment has been tested
by the manufacturer and found to comply with the limits for a
class B digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a
residential environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications. This device complies with
part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including
interference that may cause undesired operation.
Modifications to this product without the express authorization
of the manufacturer nullify this statement.
A qualified person is one who has skills and knowledge related to
the construction and operation of this electrical equipment
and the installation, and has received safety training to recognize
and avoid the hazards involved.
NEC2011 Article 100: No responsibility is assumed by
manufacturer for any consequences arising out of the use of
this material. Control system design must consider the potential
failure modes of control paths and, for certain critical control
functions, provide a means to achieve a safe state during and
after a path failure. Examples of critical control functions are
emergency stop and over-travel stop.
This symbol indicates an electrical shock hazard exists.
Documentation must be consulted where this symbol
is used on the product.
DANGER: Hazard of Electric Shock, Explosion or Arc Flash
Failure to follow these instructions will result in death or
serious injury.
• Follow safe electrical work practices. See NFPA 70E in the
USA, or applicable local codes.
• This equipment must only be installed and serviced by
qualified electrical personnel.
• Read, understand and follow the instructions before
installing this product.
• Turn off all power supplying equipment before working
on or inside the equipment.
• Use a properly rated voltage sensing device to confirm
power is off. DO NOT DEPEND ON THIS PRODUCT FOR
VOLTAGE INDICATION
• Only install this product on insulated conductors.
WARNING: Loss of Control
Failure to follow these instructions may cause injury,
death or equipment damage.
• Assure that the system will reach a safe state during and
after a control path failure.
• Separate or redundant control paths must be provided for
critical control functions.
• Test the effect of transmission delays or failures of
communication links.
• Each implementation of equipment using communication
links must be individually and thoroughly tested for
proper operation before placing it in service.
NOTICE:
• This product is not intended for life or safety applications.
• Do not install this product in hazardous or classified
locations.
• The installer is responsible for conformance to all
applicable codes
• Mount this product inside a suitable fire and electrical
enclosure.

Product Overview
The AMP1 Series DIN Rail Power Meter provides a solution for
measuring energy data with a single device. Inputs include
Control Power, CT, and 3-phase voltage. The AMP1 supports
multiple output options, including solid state relay contacts,
Modbus (with or without data logging), and pulse. The LCD
screen on the faceplate allows instant output viewing.
The meter is housed in a plastic enclosure suitable for installation
on T35 DIN rail according to EN50022. The AMP1 can be mounted
with any orientation over the entire ambient temperature range,
either on a DIN rail or in a panel. The meter is not sensitive to CT
orientation to reduce installation errors.

minute interval, each buffer holds 60 days of data)
• Continuous and Single Shot logging modes: user selectable
• Auto write pause: read logs without disabling the meter’s data

Control Power
Direct Connect Control Power, Line to Line
Line to Line from 90 VAC to 600 VAC (UL) (520 VAC for CE). In UL
installations the lines may be floating (such as a delta). If any
lines are tied to an earth (such as a corner grounded delta),
see the Line to Neutral installation limits. In CE compliant
installations, the lines must be neutral (earth) referenced at
less than 300VACL-N.

The Control Power Transformer may be wired L-N or L-L.
Output to meet meter input requirements.
Fuse Recommendations
Keep the fuses close to the power source (obey local and national
code requirements).
For selecting fuses and circuit breakers, use the following
criteria:
• Select current interrupt capacity based on the installation
category and fault current capability.
• Select over-current protection with a time delay.
• Use a voltage rating sufficient for the input voltage applied.
• Provide overcurrent protection and disconnecting means to
protect the wiring. For DC installations, provide external circuit
protection. Suggested: 0.5A, time delay fuses rated for DC
operation at or above the supply voltage.
• Use the earth connection for electromagnetic compatibility
(EMC), not a protective earth ground.

System Power:
MX KW – The theoretical Maximum System Power is calculated by
the meter from the System Voltage, CT size, and System Type.
Power Factor is assumed to be unity. The value of System Power
is used to determine which combinations of pul se weight and

meter will see. This value is read only.

Set Phase Loss:
VOLTS - Phase Loss Voltage: The fraction of the system voltage
below which Phase Loss Alarm is on. For system types with
neutral, the Line to Neutral voltage is also calculated and tested.
If the System Voltage is 600 and the fraction is set to 0.10, then
the Phase Loss threshold will be 60 volts.
IMBAL - Phase Loss Imbalance : The fractional difference in Line
to Line voltages abov e which Phase Loss Alarm is on. For system
types with neutral, the Line to Neutral voltages are also tested.

mS/P – Minimum Pulse Duration Time: This read only value is set
by the meter to the slowest duration (in mS per closure) that will
keep up with the Theoretical Maximum System Power. The open

Pulses Per Second (PPS) is shown in yellow.
Set Demand Interval:
INTRV - The number of Sub-Intervals (1 to 6) in a Demand Interval.
Default is 1 (block demand).
SEC - Sub-Interval length in seconds. Default is 900 (15 minutes).
Set to 0 for external sync-to-comms (Modbus units only).

default subinterval is 15 minutes (at a 15 minute interval setting,
the buffers hold 60 days of data). An external timer can be used
over Modbus by setting this register to 0.
Use register 159 to turn on data logging and select either Single

information is lost. In Continuous mode, the meter continues to
record energy data as long as the meter is operating. The buffer
can only hold 5760 entries at one time, however, so when the
number of records exceeds 5760, the oldest entry is deleted to
make room for the newest.

Each buffer is user- configurable with the Modbus address of the

buffers. However, the lower 16 bits of an integer energy
accumulator can be stored in a single buffer (optional).

until the next demand subinterval. At that time, both the saved
data from the previous cycle and the new data will be written to
the log, whether the page register has been set back to 0 or not.
Error bits in the Log Status Register (160) track these conditions.
Subsequent log writes will proceed normally. Provided the log
read is concluded in less time than the demand sub- interval, this
mechanism handles the occasional collision and prevents the user
from reading data as the buffer is being updated.
The Log Status Register has additional error flag bits that
indicate whether logging has been reset or interrupted (power
cycle, etc.) during the previous demand sub- interval, and
whether the Real-Time Clock has been changed (re-initialized
to default date/time due to a power-cycle or modified via
Modbus commands).

AMP1 models are protected by a user configurable passcode. The
meter supports variable CTs and PTs, allowing a much wider
range of operation from 90V x 5A up to 32000V x 32000A. To
promote this, the meter permits variable scaling of the 16-bit
integer registers via the scale registers. The 32-bit floating point
registers do not need to be scaled.
Integer registers begin at 001 (0x001). Floats at 257 (0x101).

The following table lists the addresses assigned to each data
point. For floating point format variables, each data point
appears twice because two 16-bit addresses are required to hold
a 32-bit float value.

Units Lists the physical units that a register holds.
Scale
Factor
Some Integer values must be multiplied by a constant scale
factor (typically a fraction), to be read correctly. This is done
to allow integer numbers to represent fractional numbers.
Range Defines the limit of the values that a register can contain.
