Power on site: 1-phase, 3-phase and rated current

The grinders, by rated current

• Husqvarna PG 280 — 1-phase 230 V, 13.4 A
• Husqvarna PG 450 — 1-phase 230 V, 13 A
• Husqvarna PG 400 — 3-phase 400 V, 7.31 A
• Husqvarna PG 530 — 16 A on 3-phase, 14 A on 1-phase
• Husqvarna PG 680 — 3-phase 400 V, 27 A
• Husqvarna PG 820 — 3-phase 400 V, 27 A
• Husqvarna DC 6000 — 3-phase 400 V, 15.4 A

More power can mean less current

Look at PG 280 and PG 400. PG 400 is the more powerful of the two — 4 kW versus 2.2 — but draws less current: 7.31 amperes versus 13.4.

The reason is that PG 400 runs on three-phase 400 volts. The same power spread over three phases and a higher voltage gives a lower current in each conductor. A larger machine can therefore be easier on the electrical installation than a smaller one — provided there is three-phase power on site.

Add up what runs at the same time

The grinder does not run on its own. PG 680 draws 27 A and the DC 6000 dust collector draws 15.4 A, which puts you over 40 amperes on the same circuit. At the other end of the scale are PG 280 at 13.4 A and a DC 1400 on ordinary 1-phase.

Poker vibrators do not plug straight into the mains

Poker vibrators running at 42 or 48 volts need a frequency converter. The important thing is that the converter's input current — not the output current — is what your installation sees:

• Mini 10 — 230 V in, 42 V / 200 Hz out. Input current 5 A (max. 7.8 A), output current 16 A (max. 25 A). One outlet, 9.5 kg
• Mini 24 — same voltages. Input current 7.5 A (max. 13 A), output current 25 A (max. 40 A). Two outlets, 24 kg
• Swepac PVCE 1.5 — 1.5 kVA, 230 V 1-phase in, 42 V / 200 Hz out, output current 21 A
• Swepac PVCE 2.5 — 2.5 kVA, 230 V 1-phase in, 42 V / 200 Hz out (240 Hz on a 60 Hz grid), output current 35 A

Or a poker with the converter built in

The PVEL series has the frequency converter built in and plugs straight into an ordinary 230 V socket. The current draw is 1.9 to 4.8 amperes depending on the poker diameter — well within an ordinary circuit. The converter box is IP 67.

The power trowels

Swepac TR 600E runs on 1-phase 230 V. TR 950E is three-phase, with infinitely variable speed from 40 to 130 rpm and soft start. Soft start means that the machine starts gently and ramps the speed up from zero to the set speed.

When you contact us

Tell us what is available on site: how many amperes the circuit is fused for, whether it is single-phase or three-phase, and how long the cable is from the connection point to where you will be working. These three details determine which machines can be used there.
