    Default Laser power supply load for CNI LP-series lasers?

    I'm probably going to be ordering a couple of CNI LP-series lasers for my RGB projector. The highest power will probably be a 500mw 532nm.

    Does anyone by chance know (roughly) what the power supply load rating is on these (Amps or watts)? I'll be using 115VAC as the "mains" power, and want to be able to control power to the lasers via a key switch. I'm trying to find out if I'll be able to switch power to all 3 lasers directly through the key switch, or if I'll need to plan on using a power relay.

    Thanks!

    I bought a keyswitch through Newark, rated at 5A 120V and power 2 Marconis and a 3.7V 2A 'pointer' . At the 'mains' the current draw is less than after the transformer/bridge/caps/reg. (PSU) I just run the 120VAC thru the keyswitch 1st then branch everything off from that.
