SAMPLE SPECIFICATIONS FOR MODEL A33
The charger to be furnished shall be the La Marche Mfg. Co. Model A33 or approved equal. The charger shall employ
transistor controlled magnetic amplifier circuits to provide continuous taper charging. This charger shall maintain rated
output voltage within I 1% from no load to full load with A.C. input variations of ::10%.
This charger shall have:
1.
2 ranges. Float at 2.17 V.P.C. and Equalize at 2.33
V.P.C. on lead-acid batteries. Both settings
adjustable from face of panel. (Nickel cadmium
1.4 V.P.C., float 1.55 V.P.C. equalize.)
2. Automatic A.C. line compensation.
3. Automatic overload protection (current limiting) 4.
Automatic D.C. voltage regulation.
5. Silicon diode full-wave rectifiers.
6.
Automatic surge suppressors.
7.
Power failure relay with remote indication connect
ing terminals. Single form "C".)
8.
D.C. ammeter and voltmeter with 50 millivolt
movement, 2%accuracy.
9.
Fused A.C. input and D.C. output. Separate, dual
fused output load terminals.
