Standard models superseded by Sentinel 300P

The Computronic Guardian range provides high-rate, multi-stage charging for heavy duty batteries, used in industrial applications such as engine starting for diesel driven pumps, fire pumps and power generators.

High impedance transformer technology gives a high capacity, low ripple charge output that gives safe and reliable charging for all battery types, vented or sealed, lead-acid, VRLA or NiCd. Additional relay outputs are provided for signalling of charge fail, high volt and low volt faults.

The Guardian range is UL 1236 and CSA22 approved (click here for certification), and available in open-frame or wall-mounted variants.

Features:

• UL-1236 and CSA approved
• 12/24V, 20A/10A ratings
• Intelligent, multi-stage charging
• Low output ripple (<1%), suitable for
  vented or sealed lead-acid or NiCd cells
• NFPA110 compatible alarm relay outputs:
  charge fail, low volts, high volts
• Auto boost: auto or manual boost initiation, then automatic return to float charging after boost completion
• Temperature compensation of output voltage
