MODEL i312 POWER SUPPLY & POWER ADAPTOR CABLE PRODUCT LIST > i312 >
The Model i312 Power Supply provides +5, -12 and +12 Volt regulated DC power
to a 5pin DIN 41524 Connnector.
For details showing how the i312 is typically used in an
instruNet system, click here.
As noted in the below table, the i312 is available with either a USA (#iNet-312.8) or European (#iNet-312.8eu) power plug. The photo to the right shows a USA plug.
Power Supply, 110/220VAC, 5V/3.5A, +12V/1.5A, -12V/0.8A, USA Nema Plug.
Includes one i300 power adaptor cable to cable power to instruNet network.
Same as iNet-312.8 described above, yet with 2 prong European
CEE 7/7 Plug.

i312 Power Supply Specifications
Input voltage is between 100 VAC and 240 VAC, ≤ 1 Amp.
DC regulated output voltages are listed below. The i312 product labels shows higher maximum currents, yet to keep
the i312 supply from getting quite hot, we recommend using it at the below maximum currents.
+5.0 ± 0.25 Volts at ≤ 3.5 Amps
+12.0 ± 0.5 Volts at ≤ 1.5 Amps
-12.0 ± 0.5 Volts at ≤ 0.8 Amps
Output ripple and noise is < 1.0% peak-to-peak of the DC voltage
(e.g. < 50mVpp on 5 VDC output).
The Model #iNet-312.8 provides a USA Nema Plug
and the Model #iNet-312.8eu provides a European CEE 7/7 Plug;
as noted in the above table.

Operates at ambient temperatures between 0° to 70°C.
One i300 power adaptor cable is included with each i312.8 package.
The i312.8 Power Supply and i300 Power Adaptor Cable are compatible with:
One i300 Power Adaptor Cable is included free of charge with the i312 Power Supply package
and is used to cable power to downstream instruNet Devices.
The i240 USB controller needs an i300 version ≥ 4 (manufactured ≥ 2010,
on cable shows "#iNet-300 v4")
due to the fact that ≥ v4 contains an additional circuit
that provides 5V power to the i240.

Typical i312.8 System
Pictured below is a typical system that uses the i312.8 Power Supply and
the i300 Power Adaptor Cable. In this example, the i300 Cable attaches an i2x0 controller
and the i312.8 power supply to an i410 Interface Card.
The i410 card sits in an i400 Card Cage along with an i430 A/D Card.
