Set of modular electric machines

POWER SUPPLY UNIT WITH DIGITAL INSTRUMENTS MOD. KMEC-PS/EV
This unit is universal for all the KMEC machines and it can output all the necessary AC and DC voltages. Moreover it is provided with the necessary electric instruments for the measurements of the parameters of the machines: a multifunction instrument for AC (V, I, W, VAr, VA, Frequency, Power Factor, THD% etc…, per phase, and equivalent for the three phases) – 20 A max., and 2 instruments for DC (V, I, W) – 20 A max. Output voltages:

• 0-48 VAC/10 A
• 0-48 VDC/10 A
• 24/42 VAC – 16/10 A
• 21-0-21 VDC/10 A

Protections with TMCB + overall ELCB and fuses on the very low voltage outputs, Safety terminals of 4 mm; with 3 single- phase universal sockets of 230 V – 10/16 A and a 3ph universal socket of 3×400 V/N/PE – 16 A
Supply voltage: 3 x 400 V-50/60 Hz

LOAD / STARTER MOD. KMEC-LS/EV
This unit is the variable R-L-C load for the generators. This separate unit enables the step variation of the load. Capacitors for single-phase motors are included.
It also includes a three-phase rheostat for starting DC motors, the wound-rotor motor and for the start with stator resistance.
Resistive load: 7 steps with max. 260 W (possibility of star, delta and AC/DC single-phase connections)
Inductive load: 7 steps with max. 260 VA at 50 Hz (possibility of star, delta and single-phase connections)
Capacitive load: 7 steps with max. 260 VA at 50 Hz (possibility of star, delta and single-phase connections). 22-45-68-90-113- 136-160 μF (per phase) can be applied to single-phase motors, with possibility of doubling and tripling these values by the parallel connection of 2 or 3 phases.
Starting rheostat: three-phase rheostat 0…30 Ω / 3…1 A per phase.

BASE WITH PROTECTIONS MOD. KMEC/EV
Over this base, common to all set, it is possible to place up to two machines with the related mechanical protections. This base of anodized aluminium is provided with slides to simplify the assembly of the components, the coupling between the machines and the application of the protections for the couplings.
Dimensions: 800 x 200 x 320 (h) mm
