INV2500 & INV5000 SERIES

OPERATING MANUAL

7.0 DESCRIPTION OF OPERATION

7.1 The INV2500 and INV5000 Series employ MOSFET and IGBT power semi-

conductor switches with advanced, high-frequency, pulse modulation tech-

niques to produce a low-distortion, 50 or 60Hz sine wave output with 90%

efficiency and 7VA per cubic inch power density. A synchronization circuit

lets two or more inverters operate in parallel with their outputs in phase-

synchronization and current shared.

7.2 The INV5000 consists of two INV2500s operated in parallel for 115VAC

output or operated in series for a 230VAC output. The parallel or series

connection of the units is made internally. Each of the two inverters has its

own input and output breakers, indicator LEDs and Form C relay contacts.

8.0 FRONT AND BACK PANEL DESCRIPTIONS

8.1 Figure 2 shows the front and back of an INV2500. On the left side of the front

panel of the INV2500 is the input circuit breaker. To the right are the two

cooling fans and the output circuit breaker. Above the output breaker from the

top are the green LED indicators for Input OK, Sync OK and Output OK.

8.2 On the INV2500 back panel at the upper left is the sync terminal which is a

BNC connector. Below that is a no. 8-32 stud and nut for chassis ground

connection, then a 3-terminal Type 602 Spring Con connector for easy con-

nection of wires to the Form C Relay contacts. Below this are three Ander-

son-Type connectors for the AC output (top to bottom): green (ground), white

(neutral) and black (line). On the right side of the inverter are three larger

Anderson connectors for the DC input. From top to bottom they are: green

(ground), red (DC Return) and black (-48V Input).

8.3 Figure 3 shows the front and back of an INV5000. Each front half (side A or

side B) of this inverter has an identical layout to the INV2500. The back panel

has a transparent plastic safety cover.

8.4 On the INV5000 back panel to the left are the AC output screw terminals. At

the center are the Form C relay contacts N.O., C and N.C. for each side (A

and B) of the inverter. Below these is the BNC sync connector. To the right

are the input bus bars with no. 1/4-20 studs. At the far right is the no. 10-32

stud chassis ground connection.
