I just received my trannies from Edcor.
Two each of XSE15-8-5K, GXSE10-8-5K and GXSE15-8-5K.
The XSE15 and GXSE are the same size, and the GXSE is considerably larger, about the same dimensions as a Hammond 125ESE or MQ RH-60.
In order to be able to plug them into SE CAD, I needed to measure the primary DC resistances, and for now, SWAG the primary inductance.
Note: I have measured some SE OPTs with known inductance values, as a "control", in order to verify that I am getting reasonably accurate measurements
Here's what I got:
XSE15-8-5K: Primary DCR 120 ohms, inductance 12 H, Max I 75 mA DC, 50 mA AC.
GXSE10-8-5K: Primary DCR 244 ohms, inductance 20H, Max I 60 mA DC, 40 mA AC.
GXSE15-8-5K: Primary DCR 156 ohms, inductance 20H, Max I 75 mA DC, 50 mA AC.
Secondary DC resistance is about 0.3 ohms for the 15s, and about 0.5 ohms for the 10.
I SWAG'ed the primary inductance by factoring in the lower freq response (40 or 70 Hz) and applying 5000 ohms to that frequency.
Applying Ohm's Law, L = 5000 / (6.28 X F in Hz). Rounding to the closest interger produces 12H for the XSEs, and 20H for the GXSEs.
I will be able to measure the actual induictance sometime next week when I'm back in NC, and can use my LCR bridge.
The current ratings were taken from old data provided on the earlier incarnation of the Edcor website.
Please feel free to add more "basic specs" for other EDCOR trannies, to this topic.
Update 14-June-2009:
The actual measurements (at 100 Hz) for both of the 5K GXSEs is 17H, and only 7H for the XSE15-8-5K. Looks like the GXSEs are the way to go...
