1 Introduction
The LA Series Stand-Alone linear amplifier system is an AC line powered unit based on the LA series
current-mode linear amplifiers.
Some of the key features of this system:
 Available in 4 power levels
 Available in single/two-phase or 3-phase models
 Commonly available front panel connectors for easy wiring
 Single phase 110 or 220 VAC input is only power required for operation
 All required power supplies are contained in the box
 Factory configurable transformer for various bus voltage options
 Front panel status indicator shows amplifier status
 Integrated fans provide sufficient cooling for most applications
 USB or RS-232 communication capability
 Flexible mounting options for bottom or side mounting
 Simple setup and operation
Since the Stand Alone contains a LA amplifier module, we recommend referring to the LA Series
Technical Reference manual for the modules as well. That document is available on our website.

1.3 Safety Information
Read this information before operating this system.
1.3.1 Grounding
The AC power connection to the box must have a connection to ground.


 CAUTION 


The LA StandAlone must be plugged into a properly grounded AC outlet.
Failure to provide this ground could result in a fatal electric shock.
Verify ground continuity to all metal pieces on the system.
Metal components bolted only to granite may not be grounded. Black anodized and
painted surfaces are not conductive.
1.3.2 Hazardous Voltage Information


 CAUTION 


Hazardous voltages are present at the motor output terminals and within the sheet
metal enclosure. Disconnect the AC power before plugging / unplugging any
connections or before servicing or disassembling the enclosure.

2.2 Selecting a mounting area
The unit should be mounted in a solid, clean, dry location with adequate ventilation.
Avoid mounting areas that:
 Obstruct the intake or exhaust of the internal forced air cooling.
 Allow dust, debris to enter and contaminate the cooling capability of the drive.
 Have humidity above 80% or are susceptible to moisture or coolant.
 Are prone to corrosive or flammable materials.
 Have an ambient temperature higher than 85°F (30°C).
 Vibrate, are susceptible to vibration or that could transmit the cooling fan vibration to sensitive
test equipment.
Note: The StandAlone’s allowable power output is limited by the amplifier heatsink temperature. Any
reduction in cooling capability will be directly proportional to a reduction in performance.

2.3.1 AC Input
The LA Stand-Alone amplifier can accept AC input voltages of 100 – 120 and 208 - 240VAC at 47 – 63Hz.
Note that the Stand-Alone amplifier utilizes an unregulated linear power supply. Therefore a higher AC
input (for a given range) will provide a higher voltage to the spindle and allow the spindle to reach higher
velocities.
The AC Inlet should be configured per the table below.
Fuse /
Fuse Block Value in Window
Input AC Voltage Ranges
(47-63 Hz)
Fuse Value 115V / 230V Input Minimum Input Maximum
8A 115 100 120
4A 230 208 240
Figure 3: Suggested Fusing for AC Input
2.3.1.1 Changing the AC input configuration
1. Remove power from the AC Inlet
2. Use a flat tipped screwdriver to open the window that covers the red voltage value.
3. Use the screw driver to remove the fuse block.
4. Use the table above to determine the correct fuse value.
5. Reinstall the fuse module such that the correct voltage value will show through the window.
6. Close the window.

2.4.7 Signal Connector Electrical Interface
The following drawings illustrate the electrical interface for the J8 & J9 signal connectors. Note that there
are 2 configurations available from the factory, one with optical isolation and one without. Please be sure
to use the correct drawing. Also note that J8 can be either DB15M (male) or DB15F (female).
2.4.7.1 J8 & J9 Electrical Interface, Optically Isolated
For the optically isolated version of J8, Opto Common is pin 14 and can be any voltage in the range 5-
24vdc. Active signal inputs are low referenced to the supply providing the Opto Common voltage.
Alternatively a common ground can be provided on pin 14 and 5-24vdc can be used to activate the
individual inputs. Note that the Fault output is open collector with no internal current limiting
resistor. The user must provide an external current limiting resistor to limit current to no more
than 200mA.
Note: Pin outs are shown for DB15M connector option. Refer to 2.4.8 or 2.4.9 as appropriate.
